No entry
No admittance to unauthorised personnel, usually shown as a red circle with a white rectangle across its face. It is often used for one-way traffic.
Wrong way
These signs denote that the road is only for traffic coming in the opposite direction. Used at intersections to roads with one-way traffic or ramps.
Road closed
No admittance for vehicles. It used on closed roads.
No straight ahead
Traffic is not permitted to continue straight, and must usually turn. These may occur at an intersection with incoming one-way traffic.
No motor vehicles
Motor vehicles are not permitted in this region.
No motorcycles
Motorcycles are not permitted in this area.
No heavy goods vehicles
Heavy goods vehicles are not allowed
No buses
Buses are not permitted.
No pedestrians
Pedestrians are not allowed on the road, but may use a footpath instead.
No pedestrians or bicycles
Pedestrians and bicycles are not permitted, but may be allowed on a footpath.
No right, left, or U-Turn
Either for all vehicles or with some exceptions (emergency vehicles, buses). These are usually to speed up traffic through an intersection or due to street cars or other right of ways or if the intersecting road is one-way. Indicated near-universally by an arrow making the prohibited turn overlaid with a red circle with an angular line crossing it.
No overtaking
Either overtaking is prohibited for all vehicles or certain kinds of vehicles only (e.g. lorries, motorcycles, etc...). 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 triangular (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, when 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).
Speed limits
See: Speed limit Used to indicate a maximum speed limit. The indicated limit is in mph in the USA and the UK, and in km/h in all other countries.
Weight limits
Used denote maximum weight for bridges.
Width limits
Used to denote maximum width on narrow roadways.
Height limits
Used to denote height limit on bridges and underpasses
Length limits
Used to denote maximum length.
No Horns
Sounding your horn is not allowed for vehicles in some areas, most commonly in school zones, villages, or near hospitals or churches.
No parking
Amongst one of the most familiar signs, this sign is used where parking is prohibited. Usually shown as a red diagonal bar inside a blue circle with a red ring in Europe and parts of Asia, and a 'P' in a red circle with a cross through in North and South America, elsewhere in Asia, Australia, Africa and Ireland. The no parking sign is a part of controlled parking zone sign, which is obsolete in Belgrade from 1997.
No stopping
This sign is used where parking and stopping is prohibited. Usually shown as a red cross inside a blue circle with a red ring in Europe and parts of Asia, and a 'E' in a red circle with a X through in South America.
Stop at customs
Stop at customs that are used at border crossings, toll roads or police.
