Enhancing motorcycle conspicuity – emergency response & at the roadside.


Ambulance Visibility LogoLast week, I was at an intersection in Sydney waiting for a red light to change. Off to the left and without warning, a white blur appeared in the corner of my eye.  It took several seconds to recognize what was happening but by then the motorcycle had weaved its way across two-thirds of the intersection. The bike sped out of view; a blue masthead lamp mounted on the rear of the bike flashed – just once. The motorcycle rider, a Police Officer, was responding to an emergency call. There was no wail of the siren to be heard inside my car, no other timely warning; more important, there was no obvious indication that the bike was an emergency vehicle.

The police motorcycle was engaged on a vital task; but painted bare white and travelling at high-speed it looked just like many other motorcycles found on the road (image at right). The blue chequered bands and the miniature police badges visually morphed into an indistinguishable blur. Small complex patterns can have the same effect – even turning some designs into camouflage (see image left below). Both the chequered and the miniature permutations of the Battenburg marking scheme are remarkably effective in breaking up the bike’s visual profile (especially when the bike is seen from the front). All this significantly increases the time taken by drivers to detect and recognise a motorcycle on response duty, thus reducing the valuable time they need to avoid the bike.

Furthermore, most motorcycles used by emergency services lack suitable mounting points for the warning lights; thus response motorcycles  tend to display only a minimal number of lamps – often just a single masthead lamp plus several other smaller lights facing the front and rear. The police rider on this particular day was wearing a fluorescent vest (enhancing his conspicuity) but this vest had no distinguishing markings and was again identical to the vests worn by scores of other ordinary bike riders.

In simple terms, significant opportunities to moderate the risk to Emergency Service riders while simultaneously enhancing the conspicuity and recognition of the motorbikes are often overlooked.

Compare the motorcycles described above with the London Ambulance Service (LAS) motorcycle in the photo at right. The LAS bike is painted one colour of yellow-green with retro-reflective fluorescent panels added to the body. The bike is visualised as a complete and recognisable object. The fluorescent panel markings “glow” in the light of dawn & dusk when thy are most needed. When the bike is seen from any angle the yellow-green colour clearly identifies the bike as an emergency response resource amongst other vehicles in traffic.  There is no need for identification patterns and the small NHS and LAS labels are all that is required.
