Speed plays an important role in traffic collisions. It affects the probability of being in a collision and is most directly linked to the severity of a collision. The probability of severe injury increases sharply with the impact speed of a vehicle in a collision. The risk is even greater when a vehicle strikes a pedestrian, the most vulnerable of road users.
The Neighborhood Pace Car Pledge Program encourages residents to take responsibility for the impact of their own driving while setting the "pace" for safer streets and more livable neighborhoods.
