Survival

What Cyclists Should Know

Bicycle safety statistics reveal a number of interesting points...

  • Most bicycle accidents involve relatively inexperienced riders.  On average, it seems to take cyclists about 10,000 miles (16,000 km) of riding experience to develop sufficient skill and defensive technique to ride accident-free for many years.
  • Bicyclists are much more likely to be involved in accidents while riding bikeways or multi-use paths than while riding on motorways.  Probably the main reason for this is that bikeways are often crowded with inattentive pedestrians and inexperienced cyclists, who make the mistake of treating a bikeway as a long, narrow playground, instead of as a roadway.  They wander aimlessly and make unexpected moves without looking or signaling, and such activity spells trouble if there are cyclists clicking along at 20 mph (30 km/hr) in the vicinity.
  • A cycling accident on a motorway is much more likely to be crippling or fatal than an accident on a bikeway.  No surprise here.  The reason for this is obvious: unlike the driver of a car protected by his massive shell of steel and glass, the cyclist is exposed and vulnerable.  Even the combined mass of human and bicycle are simply no match in a collision with a multi-ton motor vehicle.

In short, it's a dangerous and scary world out there, wherever you choose to ride—especially if you don't know what you're doing.  But by taking a few prudent steps you can even the odds considerably.

 

Learn and Obey the Rules of the Road

NOTE: Nothing on this web site should be construed as superseding the laws of the area(s) where you ride!

Laws pertaining to bicycles vary from state to state.  However, in most states bicycles are considered vehicles by law.  Where this is the case, cyclists are expected to obey all vehicle laws (except those expressly pertaining only to motor vehicles), and cyclists have the same rights on the road as the operators of other vehicles.  In addition, some localities have special ordinances concerning bicycles.  Learn and obey the bicycle laws of your state and community.

Ride on the right.  In most parts of the world outside Japan and the United Kingdom, vehicles are required to be operated on the right-hand side of the roadway.  Bicycles are no exception.  As vehicles, bicycles should be operated in the same direction as other vehicular traffic.  Riding on the left, against motor traffic, causes traffic flow to be disrupted each time a bicycle meets another vehicle.  In addition, it places the cyclist at extreme risk at intersections, where drivers waiting at traffic lights or stop signs are usually not watching for other vehicles approaching on the "wrong" side of the road.

Bicycles should be ridden in the right-most traffic lane.  In some states it is legal for cyclists to ride two abreast in a single traffic lane.  Bicycles should not be ridden in the parking lane or on the shoulder; these areas are not designed for moving traffic, and are often obstructed by parked vehicles or debris, making it necessary for the cyclist to dodge into the traffic lane anyway.  It is much safer for the cyclist to ride smoothly and predictably with traffic, than to weave in and out of traffic erratically.  Develop the habit of riding in the traffic lane, and use the parking lane or shoulder only as an emergency "bail-out" area.

The "ride on the right" rule also applies to bikeways, which are actually roads.  Cyclists should ride to the right of the center line except when passing, and pedestrians should walk on the left, as they would on the side of a motorway with no sidewalk.

Obey all traffic controls.  All vehicles, including bicycles, must comply fully with traffic signs and lights.  It is illegal for a cyclist to exceed the speed limit, to run a stop sign or a red light, to ride the wrong way on a one-way street, to cross a railroad track for which a warning device is operating, or to operate his vehicle on any walkway not specifically designated as a bicycle route.  (If you must take your bike onto a pedestrian walkway, dismount and walk it.)

Signal your intentions.  Operators of all vehicles, including bicycles, must signal all stops, turns, and lane changes.  Wandering aimlessly from lane to lane, or making unexpected turns or stops, is both dangerous and illegal, regardless of the number of tires your vehicle has.  Cyclists are required to use approved hand signals whenever appropriate.  A braking maneuver is indicated by extending the left arm downward.  A left turn or lane-change is signaled by extending the left arm straight to the left.  A right turn or lane-change is signaled by extending the left arm and bending it upward at the elbow.  In some states it is also legal to signal a right turn by extending the right arm to the right.

Use the proper lane.  Because they are usually slower than other traffic, bicycles should ordinarily be ridden in the right-most traffic lane.  However, when approaching intersections with separate lanes for turning and through traffic, the cyclist must signal his intention and (after checking for traffic) enter the appropriate lane for the direction he wants to go.

Be aware of the exceptions to the vehicle code as applied to bicycles.  In most states bicycles need not be registered and bicyclists need not be licensed; however some communities require cyclists to purchase permits to ride within the town limits.  In some states it is legal to ride a bike on a sidewalk; in others it is illegal.  In most states bicyclists are forbidden to ride on expressways—highways which cross other roads by means of over- or under-passes, and access to which is primarily by way of entrance and exit ramps rather than via intersections at-grade.  Know and comply with the laws of your state and of the communities in which you ride.

 

See and Be Seen

Unlike a motor vehicle driver, whose view of traffic and the road is obstructed at many points by parts of his own vehicle, the bicyclist has a clear field of view in all directions.  The wise cyclist learns to use this advantage to its utmost.

Watch traffic.  The sine qua non of cyclist survival is being alert to constantly changing traffic conditions.  Know at all times what vehicles are on all sides of you, including behind you.  Use your ears as well as your eyes to alert you to vehicles in your vicinity.  If you can, learn to turn your head to glance behind every few seconds without swerving.  If not, use a rear-view mirror; there are various types, mountable to handlebars, helmets, or eyeglasses.  Also get into the habit of watching for "holes" in traffic—"escape routes"—that you can use in case of emergency.

Watch the road.  The cyclist must be extremely watchful of road conditions, since even minor pavement irregularities or debris can make it necessary to swerve or stop to avoid blowing a tire or skidding.  While sand, gravel, and grooved pavement pose little problem for motorists, they can spell disaster for a rider balanced precariously on two skinny high-pressure tires, even at a modest speed of 15 mph.

Watch for special hazards.  Be alert for hazards which can trap narrow bicycle tires.  Steer clear of slotted storm drains (yet another reason to avoid riding in the parking lane or on the shoulder).  Railroad (or streetcar) tracks should be crossed at as close to a right-angle as possible; crossing tracks at a shallow angle (less than 45 degrees) can allow bike tires to drop into the flangeway between rail and road, throwing the rider and often trashing the wheel.  Beware of metal- or wooden-floored bridges; metal grids are not only hard on bike tires, but can also become very slick with oil or moisture; wooden planks running perpendicular to traffic might be rough enough to cause loss of control, while planks running parallel to traffic may have tire-trapping gaps between them; in either case, exposed bolt and nail heads can puncture tires.  Also be wary of metal maintenance hole covers, which can become dangerously slick from just a thin film of oil or a few drops of rainwater.

Be visible to others.  The narrow profile of a bicycle rider tends to make him less noticeable than other vehicles.  To compensate, wear reflective clothing.  After dark or at other times of reduced visibility, use a headlight and taillight.  Reflectors help, but only when they are in the direct headlight beam of another vehicle; on curves, hills, or at intersections that is simply not adequate.  (I have heard it said that dressing to look like a police officer on bike patrol is the only sure way to get noticed.  However, the semblance should not be overdone; you don't want to be arrested for impersonating an officer!)

 

Ride Smoothly and Predictably

Riding straight and true, and in compliance with traffic laws, serves two purposes.

Smooth riding gives the cyclist an edge in maintaining control when the unexpected occurs.  If a cyclist habitually engages in hazardous practices which consume most of his attention, an emergency situation can catch him completely off his guard and with nowhere to go.  If a cyclist should suddenly encounter broken pavement, a gust of wind, a pursuing dog, a horn-happy motorist, a mouthful of flying insects, or sweat dripping into his eyes, he is in a much better position to compensate and maintain control if he is riding smooth and straight, than if he is bobbing and weaving about.

Smooth, predictable riding also radiates an image of competence and confidence.  It commands the attention of the operators of other vehicles, and helps to keep the cyclist permanently in their view.  Predictability not only makes the cyclist more visible to motorists, but also makes him more credible as a responsible and legitimate user of the road.

 

Ride Assertively, but Courteously and Defensively

Claim your space—but be ready to yield it if necessary.  There is a tendency for cyclists, especially the inexperienced, to ride adjacent to the very edge of the roadway.  This presents a problem, in that it encourages overtaking motorists to try to squeeze by in the same lane, and also leaves the cyclist with nowhere to go when this happens.  Instead of riding on the edge line, make a habit of riding well into your lane, about 20-40 inches (50-100 cm) from the edge, which should place you about half-way from the edge to the center of the lane.  This has the psychological effect of "marking" half the traffic lane as "yours" in the eyes of following traffic.  It forces motorists to notice you and to give you adequate space, and discourages them from trying to pass when there is insufficient room to do so safely.  And it also gives you, the cyclist, a "cushion," room to duck out of the way, if an oncoming vehicle or an unexpected hazard appears, or if an aggressive motorist attempts to crowd you.

(Note that "assertive" riding is a defensive measure.  It should not be confused with "aggressive" riding, which is not only dangerous, but also tends to breed disrespect for bicyclists among the motoring public.)

Be courteous.  Look for openings in traffic and signal your intentions before making lane changes or turns.  If you are holding up traffic behind you on a road with no passing lane, periodically pull off the road and stop (after signaling) to let faster traffic go by.  When cresting a hill or rounding a curve, signal drivers behind you whether it is or is not safe to pass.

Ride defensively.  Wear an approved helmet, with straps snuggly tightened, and far enough forward to protect your forehead.  Keep your eyes and ears open, and your full attention focused on traffic and the road.  Expect the unexpected.  Give audible warning when passing.  Be alert for drivers making right turns immediately after having passed you.  Especially at intersections, watch for drivers who might not see you, or who might not realize how fast you are approaching.  Remember that drivers are human, and humans often do goofy things, whether intentionally or accidentally.  And remember that in any physical contest between a bicycle and a motor vehicle, the bicycle always comes in dead last.  Even if the motorist is at fault and is successfully sued for everything he owns, that is still poor consolation to a crippled cyclist who must spend the rest of his life in a wheelchair.

 

Choose Bicycle-Friendly Roads

If you have a choice of more than one way to get to where you're going, select a route with minimal hazards.  There are many factors which affect a road's bicycle-friendliness, including traffic density and speed, heavy trucks, road surface and hazards, number and width of traffic lanes, paved shoulders, curbs, debris, construction and detours, steep hills, crosswinds, stop signs and traffic lights, railroad crossings, pedestrians, and dogs or other animals.  Naturally, each person has his own perception of how bothersome each of these things is, so different people may have very different evaluations of the same road.

A bikeway, if one is available, might turn out to be your most desirable choice—or it might not, depending on how congested it is and how fast you ride.  Just remember, there is no law which says that cyclists must always use bikeways, just as there is no law which says that motorists must always use expressways.

 

Know a Good Bike Lawyer

Believe it or not, there are still many law enforcement officers, and even judges, who are partially or wholly ignorant of bicycle law, not to mention the mechanics of bicycle design and the physics of riding and handling.  Therefore, if you are ever unfortunate enough to find yourself involved in a point of legal contention regarding your operation of a bicycle, it would be well worth your time and effort to seek out an attorney who is well versed in the bicycle laws of your state—preferably one who rides a bicycle himself / herself.
