Sometimes drivers on the road can just be too slow, and well under the set speed limit.
Some Kiwi drivers are known to get so frustrated they'll unsafely overtake them.
Infact, this happens so often Kiwi police are finally going to do something about it.
Stuff spoke with Tasman road policing leader Grant Andrews who explained slow/incosiderate drivers are an issue year round, but over holiday periods it's particularly accentuated.
"It's about making people aware," Andrews said. "The problem with impeding the [traffic] flow is people tend to make crazy decisions to overtake in areas where you wouldn't ... even sometimes on yellow lines."
"Look behind you [and if] there's 20 cars and there's been provision for you to pull in and let these people pass safely, do so."
While the focus is on safety for the police's summer campaign, slow drivers could be facing $150 fines and the loss of 20 demerit points if they don't let people pass them or refuse to move into a slow vehicle bay.
Good on the boys (and girls) in blue.
