Traffic collisions are a leading cause of death and injury in California and the number one cause of death for people between the ages of one and 44. High-visibility enforcement programs (HVEs) are administered nationwide by the National Highway Traffic Safety Administration, and combine intensive enforcement of a particular traffic safety law with widespread media and public education campaigns. HVE programs have been shown to be effective in reducing alcohol-impaired driving and promoting seat belt use.
