The OPP Highway Safety Division is reminding the public to keep your four-way flashing lights off when driving in the snow, even if driving conditions aren’t ‘ideal’.

While it advises against using four-ways unless necessary, it said you should always have your full headlights and taillights on in bad weather, day and night.

“You can use your four-way flashing lights momentarily if you’re coming to a sudden and unexpected slow down or stop on the highway,” OPP wrote on X.

“Only use four-ways continuously when your vehicle is the hazard. For example, stopped and blocking a live lane.”
