Drivers of commercial vehicles may be subject to bans that do not apply to other vehicles. These bans may apply to particular vehicle classes or to larger vehicles. Regulatory traffic signs mark the beginning of the ban. If the ban applies to your vehicle (including any load), you must not drive past the sign or drive on the road to which it applies.
Supplementary plates may give additional information or exemptions to the ban.
Commercial vehicles may also be subject to stopping and parking restrictions (see pages 90 to 93).
Medium and heavy goods vehicles, buses, recovery vehicles, and any motor vehicles towing a trailer or another vehicle are prohibited from using the right most lane of an expressway where there are three or more lanes open for use, unless you are heading for a right side exit. The above restriction also applies to light goods vehicles driven by holders of probationary driving licence.

Restricted headroom
![Restricted headroom illustration Restricted headroom illustration](/filemanager/en/content_338/89g.gif)
A bridge or other structure over a road may restrict the actual headroom available. The restriction may be temporary due to bridge or other construction works. A warning sign will indicate the maximum headroom on that part of the road.
Advanced warning of restricted headroom may be given by a 'Restricted headroom ahead' warning sign with a supplementary plate showing the distance to the restriction. Alternatively, the warning sign may be shown on an advance direction sign.
