What Are the Running Light Laws for a Semi Truck?

Safely operating a semi-truck includes knowing all the traffic and lighting laws to ensure that everyone on the road is safe and secure. The following is some information about the lighting regulations for trucks so that you can make the best decisions for driving. 

Existing federal laws automatically carry over to the state. 

The first thing to understand as a truck driver is that the federal truck lighting regulations will automatically transfer to the state. In other words, the state will automatically adopt truck lighting regulations. Also, if there is no federal regulation about a specific type of light, then the state’s laws will apply in that situation.  

Lights must conform to the law’s standards.

All lights for semi-trucks must adhere to the regulations set forth by the government and match the required specifications before they can be sold and used. This rule ensures that all products can provide adequate lighting. 

All lights must have a permanent attachment. 

Another regulation says that all lights should be permanently placed on the truck. These lights must be placed on the vehicle to be perpendicular to the truck’s centerline. 

All lights must function all the time.

The truck’s lights need to function well at all times. The law ensures that every person on the road has the highest possible chance to stay safe and avoid collisions. Brake lights should come on when the pedal is depressed, and the hazard lights and turn signals should blink accordingly when someone activates them.

The headlights must also be working correctly at all times. However, no regulations specify whether clouded lenses or improper placement would cause a problem with the law. 

At least two lights must be on the back of the trailer.

Two lights must be on the vehicle’s trailer in the rear area. The driver can add additional lights if desired, but at least two must currently exist. 

Five amber lights must be on the front of a semi-cab.

The law demands at least five amber lights on the front of the vehicle.

Now you have a good idea of your lighting arrangement on your semi-truck. Check with the state regulations for additional information and fortification about the appropriate ways to set up the lighting for the truck.

By delving into the rules, you’ll avoid being pulled over, reprimanded, and possibly forced to pay consequences for making unsafe choices. Have your vehicle regularly inspected to receive notification of blown lights.
