Police have warned Redland drivers to think twice before getting behind the wheel after drinking alcohol over the long weekend.
There have already been five deaths on roads in Redland City this year.
Transport and Main Roads Minister Scott Emerson said he wanted drivers to remember the Queen's Diamond Jubilee long weekend for all the right reasons.
Statistics showed alcohol was a factor in 17 per cent of all crashes resulting in serious casualties during the 2010 Queens's Birthday long weekend.
"It might be tempting to have a few more drinks to enjoy the upcoming break, but a lapse in judgement could lead to deadly consequences on our roads," Mr Emerson said.
"Last year, drink driving was the top killer on Queensland roads, contributing to one in five deaths.
"It's alarming when you think about how avoidable many of those crashes could have been if drivers had refrained from drinking before getting behind the wheel.
"Plan ahead and think twice before you drive after drinking. Arrange a designated driver, book a cab or seek an alternative means of transport to avoid driving under the influence of alcohol.
"And most importantly drivers, especially young drivers, should never let anyone pressure them into driving if they have been drinking.
"Learner, provisional and probationary licence holders and novice motorcycle riders need to remember they must have zero Blood Alcohol Concentration all times."
Mr Emerson said estimating how much alcohol you could consume before being over the legal limit of 0.05 was extremely tricky and varied considerably depending on body weight, height, metabolism, previous meals and medications.
"Party hosts should take some responsibility as well and keep an eye on guests who may not be right to drive," Mr Emerson said.
"Insist on calling a cab for your guests or set up a carpool with others who are able to drive.
"Keep an eye on the size of the drinks you pour for your guests, make non-alcoholic drinks available and ensure a steady supply of food is served to help slow down drinking as well."
Queensland police officers will be out in force during the Diamond Jubilee long weekend and will stop motorists, truck drivers and motorbike riders randomly to conduct alcohol tests.
