A Mexican-roadblock occurs on a two or more lane road where 2 (or more) cars are traveling next to eachother at the same speed (usually under the speed limit), not allowing the following traffic to pass. Most noticeable on the highway in a light traffic situation, where two cars stop the flow of traffic wishing to pass.
