Road signs in Jamaica are standardized by the Traffic Control Devices Manual developed by the Ministry of Transport and Mining (formerly the Ministry of Transport and Works).
The symbols used in road signs are similar to Swedish ones.
Regulatory signs are used to inform the road users of various restrictions.
Unless otherwise is indicated on an additional panel, the restriction starts to apply at the point the sign is erected.
Warning signs are used to give warning of possible road hazards that are difficult for a driver proceeding at a normal pace to perceive in time.
