Bridge Strikes

How to avoid bridge strikes


  • If the travelling height of a vehicle – HGV and PSV – is over 3 metres, it’s a legal requirement to display the vehicle’s correct maximum height in the cab
  • 43% of drivers admit to not measuring the height of their vehicle before heading out on the road
  • Remember, HGV height can change for a variety of reasons; adjustment of the 5th wheel, whether the trailer is loaded or unloaded. So always check and display correct height on headboard. You can use simple handheld devices or fixed depot installations to do this
  • Make sure an HGV’s correct coupler height is displayed in the cab after loading

Route planning

  • 52% of drivers admit to not taking low bridges into account when route planning
  • Reduce risk by careful route planning using vehicle specific sat nav systems
  • Do your homework! Atlases (remember them?) often have information on low bridge vehicle height limits. Local authorities can help too.
  • If the vehicle’s maximum height exceeds 4.95 metres, your route must be checked by relevant local authorities
  • Tell drivers to stop and seek advice on an alternative route if they are diverted from the planned route and it’s obstructed by a bridge lower than your vehicle.

...prove you have a robust policy and procedure in place.

Transmaster have anti Bridge strike policy templates available and the driver app can be used to record pre departure anti bridge strike checks.

All Policy documents can be issued and managed via the FMS and directly stored within the app for drivers to refer to as required.

It's also possible for drivers to make a declaration via the app re completed checks.

Drivers can also easily check height conversion tables within the support section of the app and see what 'your' Company procedure is, in the event of a bridge strike.

Look for the signs

  • Some, but not all low bridges, are highlighted on road direction signs, providing advanced warning of the danger ahead
  • Signs are prominently displayed on low bridges where the height is less than 4.95 metres. The signs show the maximum permitted vehicle height
  • Remember – red circle signs prohibit; red triangle signs warn


If you do hit a bridge

  • Don’t hit and run. Leave your vehicle where it is
  • Report it immediately by calling the telephone display number on the bridge’s ID plate
  • Dial 999 and tell the police
  • Keep the public away
