Frequently asked questions

Why is divided highway important for school bus rules?

On divided highways, drivers in the opposite direction usually do NOT need to stop for a school bus with flashing reds. On undivided roads, all directions must stop. The median is the legal distinction.

Can I make a left turn on a divided highway?

Only at designated left turn or U-turn areas. Otherwise, the median prevents left turns. Watch for "Left Turn Permitted" or "U-Turn Authorized" signs.

What is the difference between a divided highway and a freeway?

A freeway is a divided highway with limited access (no driveways, only on/off ramps) and no traffic signals. All freeways are divided highways, but not all divided highways are freeways.
