Information signsProhibitory signs
A prohibitory sign is a traffic sign that tells drivers what is not allowed on that specific road or in that situation. These signs impose restrictions such as no entry, no overtaking, no parking, speed limits, or bans on certain types of vehicles. Their purpose is to clearly indicate actions that are forbidden to ensure safety, maintain traffic flow, and protect vulnerable road users.
How are prohibitory signs classified in Mexico?
Restrictive signs impose regulatory restrictions, including vehicle access, dimensions and manoeuvres.
What does a no-turn sign prohibit in Mexico?
It prohibits the left, right or other turn shown at the junction or position controlled by the sign in Mexico. Follow any supplementary panel or authorised direction and choose another legal route.
Can a no-turn restriction apply only to certain vehicles or hours in Mexico?
Yes, where the local sign system provides a supplementary condition or exemption, such as a vehicle class, time or authorised access. Without a valid exception, comply with the prohibited movement shown.
