What is a CAR application?

A Corridor Access Request is the application pathway used when work affects the road corridor. It usually needs clear location, date, method, TMP and contact information before a WAP is issued.

Plain-English explanation

The key points, split into simple blocks so the page is useful without feeling like a wall of text.

01

What a CAR includes

A CAR normally brings together who is doing the work, where it is happening, what will be affected, when it will happen and what supporting traffic management information is attached. Councils and RCAs use this to decide whether the corridor can be accessed safely and what conditions apply.

02

How CAR and WAP relate

The CAR is the access request pathway and the WAP is usually the permit outcome or work authority pathway. The TMP, dates and work description need to line up across both. If the TMP changes after the WAP is issued, the WAP may also need updating.

03

Why scope alignment matters

Review delays often start when the CAR says one thing, the TMP says another and the drawing shows a third version. Aligning those details early reduces avoidable questions and means the authority can review the job as a single coherent package.

FAQ

Common questions

Who reviews the TMP or CAR?

The relevant council, RCA or network owner reviews the submission. Our role is to help make the information clearer, more complete and easier to respond to.

What do you need before starting?

Send the work location, scope, dates, site plans or markups, methodology, hours of work, access needs, photos if available, and any RCA comments already received.

Can you work with our on-road crew or traffic management provider?

Yes. Your TMP Designer focuses on the planning, documentation and drawing support around the job. If your project also needs on-road setup, equipment or training, we can keep the TMP, CAR/WAP and drawing information aligned while those field services are arranged with the right provider.
