Individual Vehicle Approval (IVA): vehicle side guards (lateral protection devices)

Guidance on using vehicle side guards to reduce the likelihood of injury to pedestrians, cyclists and motorcyclists.



To help you identify the common errors and direct you to the current published required standards.

Many of these examples will apply equally to:

  • lorries and other vehicles in the N2/3 category
  • heavy trailers and other vehicles in the O3/4 category

The lateral protection device (LPD) is there to help reduce the likelihood of injury to ‘unprotected road users’ when struck by a vehicle travelling in a forward direction. It is there to deflect and to stop people going underneath the sides of the vehicle.

The IVA manual takes the definition from Directive 89/297/EEC for ‘unprotected road users’ as:

Pedestrians, cyclists and motorcyclists using the road in such a way that they are liable to fall under the sides of the vehicle and be caught under the wheels.
