BROOKLYN - The Department of Transportation has unveiled two new zone watch trailers to help protect DOT workers on the job as part of National Work Zone Awareness Week.

Nearly two dozen DOT workers have been injured in work zones since 2009 and seven have died from work zone-related incidents in the past two decades.

The trailers are equipped with cameras and monitor speed in work zones by documenting any reckless driving and encouraging safer driving while crews are on the road. If there's an accident, the police have access to all the footage for their investigation.

The city hopes to eventually have nine trailers with cameras as part of its work zone watch program.
