Motorcyclists are the worst drivers on WA roads, closely followed by those behind the wheels of sports cars and SUVs.

A survey of 1000 drivers across Australia by vehicle navigation company TomTom Telematics has also found that nearly half of all WA motorists have been put in a dangerous situation by a commercial driver.

One in 20 admitted driving recklessly while driving a company car.

And the most annoying habit among WA motorists was other drivers who fail to use their indicators, followed by those who use their mobile phones while driving or swerve from one lane to another.

TomTom Telematics sales manager Christopher Chisman-Duffy said business owners would be surprised by the survey results and the extent to which poor driving standards could affect their companies and reputations.

“This is going to become an important factor for business, as consumers increasingly expect services delivered directly to their door,” he said.

“While WA has some of the highest driving standards in Australia, poor driving also has the biggest impact on businesses’ relationships with their customers.

“This is only going to increase as the on-demand economy continues to grow in WA.

“With motorcyclists being the main culprits of dangerous driving, it’s going to be important delivery services that use those vehicles improve driver behaviour.

“Otherwise, they’ll end up losing customers and damaging their reputation.”

It was only in WA where motorcyclists were considered the worst drivers, with 39 per cent of the vote — well above the national average of 29 per cent. Nationally, sports car drivers and SUV drivers were the worst.

In a survey quirk, motorcyclists were also considered to be the most polite drivers on WA roads. They were followed by small car and bus drivers.

When asked for their biggest gripes with other drivers, 77 per cent of motorists said drivers who failed to indicate.

With respondents allowed to list more than one gripe, 74 per cent nominated drivers who use their phone and drive, 72 per cent chose those who veer in and out of lanes and 62 per cent those who skip the queue. Not indicating was the biggest gripe nationally and in every State except Queensland.
