What is the minimum height for the carrier name displayed on the vehicle?

The minimum height for the carrier name displayed on the vehicle is indeed 5 cm tall. This requirement is set to ensure that the carrier's name is easily visible from a distance, promoting clear identification and accountability for commercial vehicles on the road. Visibility is crucial not only for compliance with regulations but also for safety and professionalism, allowing other drivers, law enforcement, and the public to clearly identify the carrier.

While the other options suggest different measurements, 5 cm provides an optimal balance between visibility and practicality, meeting regulatory standards without imposing excessive space constraints. It effectively ensures that the name can be read accurately at a sufficient distance, contributing to the overall safety of road operations.
