A special radio ad aired regularly in the early hours of the morning (between 2am and 4am). It contained beta waves, which stimulate the brain and helped keep drivers alert and awake when they needed it most.

The ad containing beta waves aired on radio stations in the early hours of the morning, between 2am and 4am – the time when drivers were most likely to be tired.

As part of Vauxhall’s commitment to constantly improve road safety, there are plans to put beta waves in every Vauxhall radio ad. Each broadcast makes the roads a little bit safer.
