A selective barrier is a physical access-control device that blocks some traffic while allowing specified road users or authorised vehicles to pass.

Common examples include fixed bollards, removable posts, folding posts, retractable bollards, gates, rising barriers and width-filtering installations.

They may prevent through traffic, protect pedestrian or cycling routes, control access to restricted areas or allow only residents, public transport, deliveries or emergency services to enter.

Not normally. The permitted users are determined by traffic signs, permits, access systems and local regulations.

Only when cycling is permitted and sufficient safe space is provided. Cyclists must follow the signs applying to the road or path.

Pedestrians may pass where pedestrian access is permitted and a safe route is available. They should not walk beneath a moving gate or through a vehicle-only opening.

Only when motorcycles are legally permitted beyond the barrier and the opening is intended for them. Being physically able to fit through does not create permission.

Emergency vehicles may have keys, remote controls, automatic recognition or another authorised method of opening the barrier. Other road users must keep the access clear.

They may enter only when local access rules, permits or traffic signs authorise them. Permission may apply only during specified hours.

A retractable bollard is a post that can rise from or lower into the road surface to control vehicle access.

It may operate through a badge, remote control, access code, number-plate recognition, timer, control centre or automatic detection system.

Only after confirming that you are authorised and the bollard is fully lowered. Do not move merely because another vehicle has activated it.

No, unless your own access is also authorised and the system clearly permits it. The barrier may rise immediately after the first vehicle.

Red lights normally require road users to stop, while another signal may indicate when passage is permitted. Follow the displayed signals and local instructions.

Stop at a safe distance and wait until it has completed its movement. Never drive, cycle or walk beneath a moving gate or across a rising bollard.

Do not force, move or drive around it. Use the intercom or contact the operator, road authority or emergency service indicated at the location.

No, unless you are specifically authorised. Removing or repositioning access-control equipment may create danger and allow prohibited traffic to enter.

No. Traffic signs and access restrictions remain applicable even when the physical barrier is temporarily open or lowered.

No. An open physical barrier does not cancel a regulatory traffic sign.

Not by itself. Drivers must follow the applicable speed limit and approach slowly enough to stop before the installation.

No. Traffic lights, priority signs and ordinary priority rules remain applicable unless another traffic arrangement indicates otherwise.

Do not stop or park where the vehicle would block authorised access, emergency services, pedestrians or cyclists.

They may be difficult to see, especially in darkness, congestion or poor weather. A collision can cause a rider to fall into nearby traffic or other obstacles.

Reduce speed, identify the intended opening and pass through in a straight and controlled line. Avoid overtaking another cyclist at the barrier.

Approach slowly, wait for the access system to respond and check for pedestrians and cyclists before crossing their route.

Stop safely, activate the hazard warning lights where appropriate and report the collision. Do not continue if the vehicle, barrier or access system may be damaged.
