Other regulatory signs — Minnesota Permit Test

Regulatory signs direct drivers to follow certain traffic laws, and disobeying one can bring a citation and a fine.

A regulatory sign is the law written on a post, which is why ignoring one is a violation.

Regulatory signs direct drivers to follow certain traffic laws. You must obey these signs to drive safely and lawfully. If you do not obey these signs, you may receive a traffic citation and a fine.

Minimum speed limits are posted on interstate freeways with controlled access, and you may only drive slower if weather or road conditions require it.

Traffic moving far below the flow is an obstacle, and the minimum is what stops that being a choice.

Do not drive slower than the minimum posted limit unless bad weather or poor road conditions make it necessary.

A roundabout lane sign shows which lanes to use for each direction, and you get into the right one well in advance.

Changing lanes inside a roundabout is not allowed, so the lane choice is made on the approach.

The signs will show you which lanes to use for different turns.

A lane-use control sign means you must turn if you are in the lane it governs.

The lane is the instruction. Going straight from a turn-only lane cuts across whoever is beside you.

Lane-Use Control Signs You must turn if you are in the specified lane.

A center lane marked left-turn only is shared by traffic from both directions and is used only for making left turns.

Both directions take turns using it, so treating it as a travel lane means meeting somebody head-on.

Center Lane Left-turn Only You must share the center lane and use it only for making left turns when traveling in either direction.

A Reduced Speed Ahead sign means a slower speed limit is posted ahead and you should begin slowing down.

The new limit starts where its own sign is, and the warning is so you arrive there already slow.

Reduced Speed Ahead A slower speed limit is posted ahead. Begin slowing down.

A diamond symbol on a sign means the lane is reserved for certain vehicles, such as cars with two or more passengers, buses, commercial vehicles or bicycles.

The lane belongs to somebody else, and using it is a violation rather than a shortcut.

The diamond symbol indicates that the traffic lane is reserved for specific use or certain types of vehicles.

Parking spaces with disability parking signs are reserved for vehicles with disability plates or a disability parking permit.

The space is wider and closer for a reason, and the permit is the only thing that says who needs it.

Parking spaces with blue handicapped parking signs are reserved for vehicles with disability license plates or a disability parking permit.

Where marked disability spaces are full, a permit holder may park at an angle across two standard spaces.

A vehicle with a ramp needs the room beside it, which is what the two spaces buy.

If designated disability parking spaces are occupied or unavailable, you may park at an angle and occupy two standard parking spaces if you have a valid disability parking permit or license plates.
