"These results from our work over the weekend are disappointing to say the least,'' she said.
"The fact that drivers are continuing to put themselves, their passengers, and all other road users at risk is not only disheartening, but truly frightening."
Steel urged drivers to plan ahead, and organise sober drivers or alternative transport if drinking, particularly as Easter approached.
"We have a long weekend coming up where our roads will be incredibly busy, and we need to reduce the risk of harm as much as possible.
"As always, police will be out in force with checkpoints and random stops, but we need people to make sensible choices and stop putting lives at risk."
