How many tail lights and brake lights must a vehicle have at a minimum?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

A vehicle must have at least two tail lights and two brake lights to ensure visibility and safety on the road. This requirement is in place because having two lights allows for better detection by other drivers, especially in low-light conditions. It also helps prevent accidents by making it clear when the vehicle is stopping or turning, as both lights signal to other road users.

If a vehicle had only one of each, it might compromise safety, as it wouldn't provide sufficient warning to those around it about the vehicle's presence and intentions on the road. Regulations typically specify that these lights should be mounted in such a way that they are clearly visible from a certain distance. Therefore, two tail lights and two brake lights provide a more reliable means of communication for drivers.
