Emergency doctors are pleading with motorists ahead of what is traditionally one of the most dangerous times to be a cyclist in Queensland.

More than 130 riders have died on the state's roads in the past 15 years, more than in any other state except New South Wales.

Bicycle Queensland chief executive Ben Wilson said there didn't appear to be a huge difference between drivers from Queensland and other states but roads were a problem.

"We probably have some of the worst roads in the nation because they're narrow and we're fitting a lot of traffic into them," he said.
