States that are experimenting with identification programs for teenage drivers that involve sticking a decal on their license plates don't necessarily see a drop in the number of accidents, or citations involving teen drivers.
Those interesting findings came from a study conducted in New Jersey, which is the only state in the country that currently requires novice drivers to have an identifying red decal on their license plates. Anyone who is driving with a learner's permit must have the decal on his license plate.
The researchers went through accident rates as well as citation rates involving teenage drivers in the years following the decal law which was passed in 2010. The researchers found that the decal program has not necessarily reduced the rate of accidents involving teenage drivers.
The researchers believe that the decal program has not had any kind of impact on crash risks involving teenage drivers, because these teenage drivers are driving under supervision. They can only drive with an older adult, or caregiver in the car with them. That supervised driving probably reduces the risk of risky driving and, and minimizes the risk of citations and accidents.
However, the researchers also agree that it is still far too early to tell whether there are any long-term benefits from having such identification decal programs, for teenage motorists. One thing seems to be certain from the study. Teen drivers seem to do much better at driving safely when they are supervised by parents and parents take a very proactive role in their safety.
If you're the parent of a teen driver, get a parent-child driving contract that clearly lays out the rules for responsible driving, and talk frequently with your child about safe driving, and avoiding dangerous driving practices.
