82. Barriers

Barriers are physical devices used to block, restrict, guide or separate traffic. They can protect road users, close roads or lanes, control access, separate opposing traffic or shield people and work areas from moving vehicles.

Road barriers may be permanent or temporary and can include gates, boom barriers, concrete barriers, movable barriers and other restraint or closure systems. Drivers must respect barriers and must not pass them when they indicate that a road or area is closed.

What are road barriers used for?

Road barriers can close roads or lanes, control access, separate traffic streams, protect work zones and prevent vehicles from entering hazardous or restricted areas.

Can road barriers be temporary?

Yes. Temporary barriers are commonly used during roadworks, emergencies and special traffic arrangements, while permanent barriers may be installed for access control or long-term protection.

May you drive past a closed traffic barrier?

No. A closed barrier normally indicates that access is prohibited or unsafe. Drivers should stop and follow any accompanying signs, signals or instructions rather than attempting to drive around it.
