what is the fatal crash rate in QLD caused by drunk or drogged drivers

In Queensland, drink and drug driving is associated with about 30% of fatal crashes , so a reasonable quick answer is that roughly 3 in 10 fatal crashes involve drunk or drugged drivers.

What the numbers mean

• A Queensland road-safety fact sheet says alcohol and drug driving is the number one contributor in approximately 30% of fatal crashes in Queensland.

• Queensland Police also state that drug use is associated with crash involvement, with a risk similar to driving with a blood alcohol level of 0.1 to 0.15%.

• A Queensland coroner-based study found 43.6% of vehicle controllers involved in traffic fatalities had either alcohol or illegal drugs detected, but that is not the same as the fatal-crash rate and should not be used as a direct crash percentage.

Best single figure

If you want one headline number for a post or quick scoop, use: About 30% of fatal crashes in Queensland are linked to drunk or drugged driving.

Small wording note

Your question says “drugged,” which is usually written as drugged or drug-driving in public-safety reports. For clarity, “drink and drug driving” is the standard wording in Queensland road-safety sources.

Source nuance

The exact percentage can vary depending on whether a source measures:

• crashes where alcohol/drugs were a contributing factor,
• deaths involving a driver with alcohol or drugs in their system,
• or coronial findings across multiple years.

TL;DR: In Queensland, the commonly cited figure is about 30% of fatal crashes involving drink or drug driving.
