Good Vibrations!

Just image driving along the road and your car starts to vibrate?

Is it an earthquake you think, a service overdue or are the wheels about to fall off?

No, it will be a blast from the latest low frequency howler being fitted to ambulances to augment their traditional lights and sirens.

These send pulses of low frequency tones every eight seconds which vibrate cars, and other things including pedestrians, within range of an ambulance on an emergency dash.

This will hopefully alert motorists who may be not concentrating on the driving task, perhaps with their car stereo's turned up too loud, or dare we say ... they’re on the mobile phone.

The Emergency Medical Services Authority in Oklahoma is among the first to be installing them in ambulances.

If they prove successful in reducing delays and intersection accident collision rates of ambulances then we can expect others to fit this latest technology.

I just can’t wait to experience the good vibrations.
