Motorists will soon see the return of the alco-blow breathalyzers on the roads, but this time it will be different.

Traffic commandant Benson Githinji said the alco-blow will be disposable and that it will be used per driver.

The breathalyzers will also have a recording machine from where a print-out will be issued after a driver has been tested. This is to avoid many unnecessary checks along the road.

The breathalyzer is used to measure the amount of alcohol that a driver has taken. One blows into the gadget and a red light appears depending on the amount of alcohol it detects in one's breath.

The gadgets came into use in 2005 but motorists complained that the traffic police officer took advantage of it to harass and extort money from them.

Githinji was speaking to matatus, bus and tour van operators at the Coast provincial police headquarters at the weekend.

He said this is in a bid to reduce the incidents of drunk driving that has cause loss of lives through accidents.

The commandant also announced that the curriculum of driving schools in the country will be reviewed. He said a re-examination of drivers will be done after every two years after acquiring the driving license.

"Some acquire the driving licenses but do not have vehicles. So they stay for as long as two years without driving. Such are the drivers who cause accidents when they get on the roads," he said.

Drivers who fail the exams will not be issued with a license or their licenses will not be renewed until they retake the exams.

These are part of the changes that Githinji said will be implemented in the traffic department to ensure sanity and order returns to the Kenyan roads.

About 3,000 people lose their lives in accidents annually in Kenya. Most of these accidents are caused by human error, according to the police.
