We all can agree that to most cyclists, safety is of high importance. Yet, many cyclists have vastly different ideas as to how to ride safely whether in traffic or even off road. Below, I make some suggestions that I hope will help to prevent bicycle accidents, particularly bicycle collisions with cars. While every situation is different, one maxim is true and that is that every bicycle rider must be constantly strategizing how to most safely reach his or her destination. Roadway hazards from cars or even the pavement are constantly popping up, and decisions need to be made quickly. Many dangers are obvious and the strategy to avoid the danger is clear. However, some common threats are often found where you might least expect them.

According to Pedestrian and Bicycle Information Center (PBIC) (,

In 2009, 630 U.S. cyclists were killed in crashes with motor vehicles. Meanwhile, more than 500,000 cycling accidents result in a trip to the emergency room each year.

George Choulos, partner at Choulous, Choulos & WyleCommon sense is your best defense to prevent bicycle accidents. While not in any way comprehensive, I’d like to point out some bicycle safety tips for you that should be obvious but are missed all too often…

Don’t ride drunk: Did you know that 1/3 of all cycling fatalities involved a legally intoxicated cyclist?

Ride with traffic: Some people think that they are safer riding against traffic since they can see the cars coming. However, the safest path is to stay as close as possible to the right, moving in the same direction as traffic.

Don’t ride with headphones: It is very important to hear all around you while operating a bicycle. Whether it be the click of a car door, or screeching tires of a speeding car, listening can save you from a serious bicycle crash.

Wear a helmet: Don’t hit the road without a helmet to protect your head. Head injuries are responsible for about 3/4 of deaths among cyclists involved in crashes. Wearing a helmet can, in fact, reduce the risk of head or brain injury by approximately 2/3 or more. [And, make sure your helmet is not on backward! It’s also important to replace your helmet every 3-5 years since the weather, sweat and hair products can reduce a helmet’s effectiveness over time.] I know that some will say that a bicycle helmet will not save you if you are struck by a speeding car, and that may or may not be true. However, there are many impacts to the head that would be less severe if a good helmet is worn. Some people argue that even saying that is a deterrent to cycling. I respectfully disagree, and I wish to promote safer riding which will in turn lead to more people riding bikes.

Be predictable: My motto "If it’s predictable, it’s preventable" holds true not for automobiles by for cyclists too. Automobiles will expect the cyclist to ride in a straight line, not weaving in and out of cars or hopping from the sidewalk into a traffic lane. There are some cases where a pothole in the road might cause a cyclist difficulty, in which case a bold and safe move for a cyclist is sometimes to ride in the lane of cars boldly. In my neighborhood in Marin County, we have a terribly rutted bicycle path and the only safe way to ride is in the traffic lane.

Be visible: To reduce your personal risk, it is best to limit riding to daylight hours and wear fluorescent colors (not white) to increase the distance that drivers can see you. Use white lights in the front and red in the rear, as well as reflectors and reflective clothing. If you have to ride at night, use a street legal light, and don’t count on motorists seeing you because there are streetlights present.

The above is by no means a comprehensive list on how to stay safe on a bicycle. These are just some hints and actual real life circumstances may dictate a different strategy. The key is to always be strategizing, weighing risks and benefits and to always be riding defensively, because, you can be injured even when you are right.

    Bicycle Safety in Traffic? It's Not About The Helmet.  

    Yes, helmets are an important backup. But helmets don't prevent collisions. When you start to ride in or near traffic, the first principle of safety becomes PREVENTING collisions.

    That begins with using basic traffic principles & FREQUENT arm-signals. Big, brief, full-arm signals are highly visible & very effective on a bike; much more so than for drivers. Flashes of motion & color catch the eye, alert drivers, cut confusion, & add width. They're seen as being a serious road user; increasing cooperation, safe passing & respect.

    ADVANCED ARM-SIGNALS (full-arm, all fingers, brief!):

    Car ahead might pull across too soon? HALT! signal.

    Cars coming up behind? A few brief SLOW-signals.

    Changing line? Heavy traffic? POINT your direction.

    Stop-Sign? At least stop pedaling, signal slow, scan.

    If most cyclists rode at just this basic level, we'd eliminate the majority of car/bike collisions. Being safe in traffic means behaving seriously.

    But to cycle in traffic at a serious ADULT level takes real training. Most people have never even heard of bike-safety training beyond a child-level bike rodeo -- & they don't even use that.

    Training in Advanced Traffic-Bicycling makes it easier & safer wherever one rides, on every road, bikelane or not.

    That begins with studying traffic-cycling & taking Advanced Traffic-­Bicycling classes nationwide from instructors certified by the League of American Bicyclists at

    Thank you for your thought and consideration.

  2. Thank you, Lauren. I agree that collision prevention is the very most important goal, and that helmets are just a back up to try to reduce injury.

    Have a nice day..
