CLOCS-A traffic management plan: what clause 5.3.4 requires

A construction traffic management plan, in CLOCS-A, is the plan the Principal Contractor keeps for how heavy vehicles move on and around the job. Clause 5.3.4(a)(i) says it includes Traffic Guidance Schemes and Vehicle Movement Plans. The Standard binds only where the client's contract requires it.

Demiton is not CLOCS-A, is not an accreditation body and accredits no one. This is an independent explainer. Every duty and item below is read from CLOCS-A Standard v1.6, published 21 April 2026, read 21 October 2026.

The short answer

Keep a construction traffic management plan that includes Traffic Guidance Schemes and Vehicle Movement Plans (cl 5.3.4(a)(i)). It is a Principal Contractor duty. CLOCS-A is a national voluntary Standard (s 1) that binds a contractor only when the client's contract requires it (s 3), or once the contractor is accredited. If the contract you signed does not name CLOCS-A, and your business is not accredited, this clause does not bind you; if it does, the plan is one of the first things a client or an auditor will ask to see.

The words that carry the duty are the two named documents. A plan that describes how traffic moves but holds no Traffic Guidance Schemes and no Vehicle Movement Plans does not meet the clause as written. The plan must also be reviewed, but the Standard states no review interval. That is a fact about the Standard, and it cuts both ways: no interval is imposed, so the interval is yours to set and to defend.

The three plan duties, by clause

Three Principal Contractor rows in this library concern the plans. The first two sit on this page; the third, the logistics management plan, has its own page because it is a separate document.

What clause 5.3.4(a)(i) asks for

The duty is to keep a construction traffic management plan that includes Traffic Guidance Schemes and Vehicle Movement Plans. Read it as a checklist of three things a reviewer can hold in their hand: a plan exists, it contains at least one Traffic Guidance Scheme, and it contains at least one Vehicle Movement Plan. The library holds the duty and its clause; it does not hold the Standard's definition of either scheme, so read the Standard for what a compliant scheme or movement plan must show.

The verb is "keep". A plan written for tender and filed does not answer it. The plan has to exist for the life of the job and match how the job runs, which is why the review matters.

The review, and the risk register beside it

Two reviews sit near the plan. The first is the plan's own: the plan must also be reviewed, but the Standard states no review interval. The second is the heavy vehicle movement risk register, which the Standard does give an interval: review the heavy vehicle movement risk register at least every six months (cl 5.3.1(a)(ii)).

A sensible reading, and it is a reading rather than the Standard, is to review the plan whenever the register is reviewed, so that the plan never lags the risks it is meant to control. That ties the plan to a six-month rhythm the Standard does state, and leaves a record that the review happened.

What a client or auditor will look for

  • The plan itself, current, naming Traffic Guidance Schemes and Vehicle Movement Plans (cl 5.3.4(a)(i)).
  • A dated record of each review of the plan, and the interval you set for it.
  • The heavy vehicle movement risk register, with the date of its last review (cl 5.3.1(a)(ii)).
  • Evidence the contract requires CLOCS-A, since that is what makes the duty bind.

How this differs from the logistics management plan

The construction logistics management plan (CLMP) is its own document, separate from the traffic management plan, and no register records when it changed, so this is recorded not_collected. The traffic management plan is about movement on and around the job. The logistics management plan, set out in Appendix C, is the wider document, and it carries its own one-month update rule (App C(j)). Keep the two apart in your document control: one revision register for each. The logistics management plan page takes Appendix C clause by clause.

What this page does not hold

It does not hold the Standard's definition of a Traffic Guidance Scheme or a Vehicle Movement Plan, the client and developer duties, or the other Principal Contractor duties in clause 5.3. It holds 3 plan duties and says whom each binds. For everything else, read the CLOCS-A Standard and your contract, and see the CLOCS-A guide for the duties the library does hold.

What this page is, and is not

It is the clause text this library holds from the CLOCS-A Standard, with whom each duty binds. It is not legal advice, it is not accreditation, and it does not score anyone's readiness. Read the Standard and the contract you signed.
