How many red or amber lights are required on tailgates?

1. One

2. Two

3. Three

4. Four

The correct answer is: Two

For vehicles that have a tailgate, it is important to ensure that they are properly equipped for visibility and safety. The requirement of two red or amber lights on tailgates is to provide adequate warning to drivers behind the vehicle, especially in low visibility conditions or at night. These lights help indicate the presence of the vehicle and can prevent accidents by making the vehicle more visible. The two lights can serve various functions, such as indicating that the tailgate is down or that the vehicle is slowing down or stopped. This is particularly crucial for larger vehicles, like trucks or SUVs, where a lowered tailgate can obscure the vehicle’s braking lights. Therefore, having a pair of lights enhances the overall safety of the vehicle by ensuring that it is easily seen and understood by other road users. Other numbers of lights, like one, three, or four, do not meet the safety standards set to provide sufficient visibility or may not serve the intended function effectively.
