10 Common TM Mistakes

10 Common Event Traffic Management Mistakes (and How to Avoid Them) This short guide is designed to help event managers understand key compliance risks in temporary traffic management (TTM). Based on real-world experience and aligned with UK regulations, it highlights what often goes wrong — and how to put it right.

Unsafe Pedestrian Crossings

Temporary crossings must use two signal heads per approach, safe crossing widths, lighting, and proper guarding.
Incorrect placement of WAIT HERE boards or ramps without protection puts pedestrians at serious risk — especially on unlit or narrow roads.

Unsafe Pedestrian Crossings

Standalone temporary Pedestrian Crossing facilities are most commonly found at events, when set up in this manner 2 light heads must be used per approach. The minimum width of the crossing should be 2.4m - this should be increased with high pedestrian flow or when cycles are using the crossing. All Temporary traffic lights placed on the highway require permission from the local authority.

The vehicle lights can be no more than 10m away from the crossing point and in cases where the light head is further away an additional one must be installed at the crossing point.  When installed at a curb ramps must be provided for wheelchair and pram users, these must be appropriately signed and guarded against passing vehicles, this makes installation on a narrow road difficult without reducing to single file traffic.

Pedestrian crossing buttons should be placed facing oncoming traffic so pedestrians are looking at oncoming traffic before they cross. When used on an unlit road temporary lighting should be provided to give a good even coverage, care should be taken to reduce glare which may distract drivers and obscure their view of pedestrians.

A new WAIT HERE board has been designed specifically for use on temporary pedestrian crossings.  Use of any other WAIT HERE board is no longer acceptable.


Summary: Temporary crossings must use correct layout, signage, lighting, and ramping.


Why This Matters: Pedestrian safety is often overlooked. Incorrect setup puts users at direct risk and can breach legal duty of care.


Key Regulations:

  • TAL 2/11, 3/11, Chapter 8, Pink Book


Common Issues:

  • Inadequate crossing widths or light placement

  • Missing WAIT HERE signage or temporary lighting on unlit roads


What You Should Do:

  • Use dual light heads, visible signage, and minimum 2.4m width

  • Install ramps and barriers on kerbed roads


Event TM Recommends:

  • Temporary crossing setup and testing

  • Event crew training on safe pedestrian movement
