🚗 Active Cruise in the Fog – Helpful or Hazardous?
With all the foggy mornings we’ve had lately, here’s a solid tip:
Turn on your active cruise control and set it to the max following distance. It can help your car detect vehicles in the fog before you even see them.
I actually use this trick myself in my Kia Cerato. And back when I was driving trucks, the European rigs like Volvos and Scanias had the same ability. There are even dashcam videos where the truck's radar system warns the driver to stop because of a crash ahead — long before the human eye can see anything through the fog.
The radar picks up vehicles much earlier, which gives you that extra heads-up when visibility drops.
But… and this is a big one:
❌ It doesn’t replace your eyes
❌ It doesn’t give you permission to fly blind at 100 km/h
✅ It’s just a tool to help, not take over
If you can’t see, slow down within reason.
If visibility’s completely gone, pull over safely, pop your hazards on, and wait it out.
Driving to the conditions will always beat relying on tech to save the day.
And while we’re talking fog — check if your car has a rear fog light.
It’s usually a single bright red light on one side at the back. A lot of people mistake it for a stuck brake light, but it’s actually there to help cars behind you see you from further away in thick fog.
So chuck on your front and rear fog lights, use your active cruise for early detection, but stay sharp and in control.
