Which type of vehicles can carry a red light visible from the front?

The correct answer is that only emergency vehicles responding to a call can carry a red light visible from the front. This regulation is rooted in safety and the need for emergency vehicles to be easily identified, allowing them to navigate traffic quickly and efficiently. When these vehicles are responding to an emergency, the red light signals to other road users that they should yield the right-of-way, which is critical for the timely response to emergencies.

Other types of vehicles, such as taxis and public transportation buses, do not have the same role in emergency situations and therefore do not have the authority to display red lights visible from the front. All motor vehicles, while subject to specific lighting regulations, do not include the right to use red lights unless they are designated emergency vehicles.
