No overtaking

Overtaking is prohibited either for all vehicles or for certain kinds of vehicles only (e.g. lorries, motorcycles). In the USA, this is usually phrased as "no passing zone" and indicated by a rectangular, black-on-white sign on the right side of the road that says "DO NOT PASS", and/or by a solid yellow line painted on the roadway marking the left limit of traffic (centerline), and sometimes supplemented by a yellow (no passing zone) sign on the opposite side of the road (where it can be seen by a driver who is attempting to pass). Conversely, where the passing restriction is lifted, a rectangular, black-on-white sign that says "PASS WITH CARE" is placed on the right side of the road, and/or the yellow centerline changes from solid to broken (indicating that passing is allowed in that direction).

Limits

Speed limits

Used to indicate a maximum permissible speed. Speed limits are posted in kilometres per hour in most countries; however, the United Kingdom and United States use miles per hour. Motorists are expected to be aware of this, as the majority of speed limit signs display only a number and no specific units, although some countries' signs do display the unit as well. In Canada, the first sign in a sequence will display km/h and subsequent signs often will omit the unit.
