Traffic Officers patrol the motorway network using high-visibility 4×4 patrol vehicles. Such vehicles are used mainly for their ability to tow, or clear broken-down or disabled vehicles to a place of safety off the carriageway if needed. 4×4 vehicles can remain mobile in flood or snow conditions, as well as being able to carry the large amount of safety and recovery equipment (including a basic 1st aid kit) that the patrols use. Such vehicles also have the advantage of visibility their size makes them more visible to other motorists when stationary on the hard shoulder. All of the vehicles are liveried with yellow and black Battenburg markings; equipped with a Sepura vehicle mounted TETRA digital radio; hands-free mobile telephone; have the benefit of red and amber LED lightbars and additional LED lights.
