In our surveys you said that you enjoy biking to work, it is cheaper than using the car and you can cut journey times by filtering through traffic jams.
All good stuff...but more and more collisions are happening to riders on their journeys to work through heavy traffic. Check - does the driver know you are there? Watch for clues that may mean the driver is tired of waiting and may grab a chance to escape from the queue, pulling out on you with little warning.
One of the major causes of biker crashes is the vehicle which emerges through queueing traffic to turn left or go straight across the junction.
