Bicycle and Vehicle Collisions
From the League of American Bicyclists, these are the top reasons for collisions between adults riding bicycles and motor vehicles. Keep in mind that over 50% of the time we fall on our bicycles, it has nothing to do with a motor vehicle. It is simply a fall caused by a curb, sand, wet pavement, obstructions, animals, pedestrians, etc. Add up the numbers and you will see that the most common denominator is the intersection.
Collisions
What happened % of collisions Fault
Wrong way riding facing traffic 14% Bicyclist
Left turn in front of the bicyclist 13% Motorist
Right turn in front of the bicyclist 11% Motorist
Left turn from the right side of the road 11% Bicyclist
Failure to yield from driveway 9% Bicyclist
Running a stop sign or signal 8% Bicyclist
Running a stop sign or signal 8% Motorist
Opening car door into path of the bicyclist 7% Motorist
Failure to yield from driveway 6% Motorist
All others 8%

Strobes for bicycle safety
Most bicycle/motor vehicle collisions would never have happened if the motorist would have seen the cyclist in time. While bright clothing is helpful, strobe lights are unsurpassed for getting the attention of increasingly distracted motorists. I've been using them for some time and they've had a dramatic effect on motorist behavior.
The following article by a Seattle cyclist/attorney goes into more details regarding why strobe lights are so important for riding safely during the day:
AN OUNCE (OR TWO) OF PREVENTION COULD SAVE YOUR LIFE
by John Duggan
Over the past two years I have investigated more than 100 bike/car incidents in the Greater Seattle area. The common thread in nearly every one of these incidents is that the car driver was not aware of the cyclist until it was too late and often not until the moment of impact. The most common accident involves a left turning car driver who simply does not see the oncoming cyclist.
Awareness is the key. Cyclists simply do not have the mass or size of a car and are essentially invisible to motorists. Furthermore, there are not enough cyclists on the roads to make an impact. The everyday car driver is not accustomed to seeing cyclists on the road and, therefore, cyclists are not on the driver's radar screen. If a car driver only sees the occasional cyclist, he/she does not have a heightened awareness or an anticipatory thought process- - "Before I change lanes, I better look over my shoulder to see if there is a cyclist to my right." Or, "Although there are no cars approaching, I better scan to check for cyclists." Until there is a dramatic increase in the number of cyclists sharing the road with cars, this automatic, reflexive thought process on the part of motor vehicle drivers will remain a distant dream.
Besides encouraging everyone we know to commute by bike, what can cyclists do to immediately raise awareness? Buy a strobe and use it as a daytime running light. I have had a small LED strobe on my bike for about a year, but until recently, I only used it at night. Motorcycles are required by statute (RCW 46.37.522) to have their headlamp on during daylight hours and most new cars have headlights that automatically come on when the car is running. The logic is simple. While daytime use of such lights does not help a cyclist or motorcyclist see any better, it dramatically increases the cyclist's visibility to others.
Over the past few years the market has been flooded with an abundance of small, lightweight and inexpensive LED flashers/strobes. Planet Bike, CatEye, Performance and NiteRider all sell models ranging from $15 to $30. These lights will run from 100 to 160 hours on two or three AAA batteries. The lights are simple to use and clip onto your handlebars or helmet in seconds.
Using one of these inexpensive LED strobes during the day is the simplest and maybe the most effective thing you can do to increase your visibility during daylight hours. Ride Safely!
