"It's important to remember predicted peak times can change based on incidents, weather and changes in driver travel patterns."
Eastern District Traffic Alcohol Group Senior Constable Andy Clinton is also advising caution around congestion, fatigue and drivers in unfamiliar environments.
"During these times police urge that all drivers be courteous, remember to share the road with others and to schedule frequent breaks."
"There are more drink-driving incidents during holiday periods and Eastern District Police will be out in force targeting these drivers and getting them off our roads over Queen's Birthday weekend."
Police will be monitoring State Highways around the region and remind drivers to follow others at a safe distance in case the driver in front stops suddenly.
"There is a high number of roadworks throughout Hawke's Bay at the moment and special care is need around these, especially at busy times such as holiday weekends. When you see a roadworks sign, always slow down and be ready to stop."
Hawke's Bay road policing manager Matt Broderick is also urging caution, especially when it comes to distracted drivers.
"About a third of death and serious injuries on the roads involve alcohol and/or drugs. Make plans to get home safely. Distracted drivers are not safe. Turn off your mobile device while you are driving. Nothing is so important as to risk not arriving at all, just to answer a message."
"The outcome of any mistake leading to a crash is always determined by the speed. More speed results in more impact forces," he said.
