Dangerous driving on Horowhenua's beaches will not be tolerated and people need to remember road rules apply, police say.
All beaches with public vehicle access are considered public roads, which means the road rules still apply, even if there is no signage.
In Horowhenua, driving is allowed on the whole coastline, with a 30km/h speed limit for all areas.
The limit was reduced from the open road speed of 100 km/h after a unanimous vote by the Horowhenua District Council just over a year ago.
Originally a proposal for 60km/h had been made, but this had been altered after the Foxton Beach Volunteer Warden Group, headed by councillor Ross Brannigan, made a submission that reducing the limit to 60km/h did not go far enough, and the default speed should be 30km/h.
