Alert cyclists are always aware of their surroundings.
They use rear-view mirrors and learn to keep their balance while looking over their shoulders. Bikes should be equipped with a white headlight and a rear reflector when ridden at night.

It is dangerous to ride bicycles on interstates and expressways.
