What is the speed limit on a frozen lake in winter?

As fast as you can go! ZOOM

The ice boats can go up to 120 miles an hour.

Whatever conditions, the car, and your balls will allow.

Lakes don’t freeze here, so I guess I’ll NEVER know; however, I do like @kritiper‘s answer!!!

Generally there is none unless someone says there is.

Uphill or downhill?

Without special equipment, I doubt that a car could travel all that fast, assuming that you start from rest. The car would immediately start skidding. It may also start spinning. I don’t know if there is any way to get out of a spin while trying to accelerate.

If you go onto the lake traveling at high speed, you could slide on the ice at close to the initial speed for a good distance.

Saw a show where some men were going 55 mph on a frozen lake as if drag racing!
Problem then becomes being able to stop on ice!

Based on @Inspired_2write ‘s answer, I did a Web search on ice drag racing and found this site The article says that cars can go as fast as about 60 mph.
