• Blue lights mean motorists should move to the side of the road.New Jersey state contour against blurred USA flag image by Stasys Eidiejus from Fotolia.com
  
  Blue light laws in the state of New Jersey require a driver to pull over if he or she sees them in the rear-view mirror. These lights allow an emergency volunteer passage through traffic. Not everyone in New Jersey can put a blue light on a car, however. There are rules.
  
  

Blue lights are for volunteers

• Blue light permits are given to volunteers in local emergency care organizations. The driver must be an active member in good standing with a volunteer fire company, or be a county or municipal Office of Emergency Management volunteer who responds to emergency calls as part of their official duties. The driver can also be a member of a first aid or rescue squad.
  
  

Only active volunteers can have a blue light

• Permits are good for four years and must be carried with the driver at all times. If the driver stops being a volunteer, he or she has 10 days to surrender the permit to the New Jersey Motor Vehicle Department.
  
  

Where to put blue lights

• No vehicle may have more than two blue lights. If only one is used, it has to be mounted on the center of the roof, in the grill no higher than the headlights, or inside the vehicle on the center of the dashboard.
  
  Two lights can be placed on each side of the windshield, where spotlights are usually mounted; on the roof as part of a light bar or as separate units, with each mounted on the roof directly over the windshield. Lights must be shielded from the driver's vision. Blue lights must be installed in the same place on each side of the vehicle. It is prohibited to place one blue light on the roof and another where the spotlight is usually found.
