Volvo has requested special exemption from Sweden's tough drink-driving laws to allow its test drivers to assess new safety systems that warn if a driver is not reacting to danger.

"It's a matter of developing technical systems that warn if the driver is not reacting properly, or if the driver is tired, sick, drunk or under the influence of other drugs," said Volvo spokesman Christer Gustafsson.

"Its all about safety, and we want to do this in a controlled environment in Sweden," Gustaffson added.

Sweden has one of the best road safety records in the world and its drink driving laws are among the toughest in Europe. Reportedly, drivers may consume no more than one beer before facing a heavy fine, while drivers caught over the limit can be sent to prison.

The heavy laws apply to both public and private roads.

The new safety system is still in its developmental stage and details remain sketchy.
