Police are urging people to take care driving back from holidays after three people died on NSW roads during the Australia Day long weekend.
"Do the right thing by yourself, your family, your friends and other road users - slow down and take extra care," Acting Assistant Commissioner Stuart Smith said on Monday.
"Take a break every two hours and remember, don't trust your tired self."
NSW Police say three people have died so far in separate crashes on NSW roads over the long weekend while 127 have been injured in 397 car accidents.
Highway patrol officers have conducted almost 150,000 breath tests during their annual four-day operation, which ends at midnight on Monday.
By mid Monday, 171 people had been charged with drink driving, while 2591 drivers had been caught speeding.
