These are the signs you'll meet every day. Stop and yield signs decide who goes first, and speed signs set limits that still depend on conditions. Some intersections and school zones have cameras that enforce the rules for you.

Know the rule

Stop sign: stop at the line, crosswalk, or corner. Look for crossing vehicles and pedestrians in all directions and yield the right-of-way.

Stop
Stop sign

Know the rule

Yield sign: slow down and let traffic that has the right-of-way cross first.

Handbook p. 114 ↗
Yield
Yield sign

Know the rule

The maximum speed limit is for ideal conditions. Slow down when the road is slippery or it's foggy and hard to see.

Handbook p. 114 ↗

Know the rule

Even under the posted limit, you can get a ticket for driving too fast for conditions.

Handbook p. 114 ↗

Know the rule

Some roads have minimum speed limits. You must travel at least that fast so you aren't a hazard to other drivers.

Handbook p. 114 ↗

Know the rule

Keep Right signs remind you to stay in the right lane unless you're passing another vehicle.

Handbook p. 114 ↗

Automated traffic safety cameras record images if you:

  • Fail to stop at a steady red light
  • Fail to stop at a railroad crossing signal
  • Exceed the speed limit in a school zone
Handbook p. 115 ↗

Know the rule

All camera locations are clearly marked. Tickets from them are mailed to the vehicle's owner.

Handbook p. 115 ↗

Know the rule

Speed warning signs recommend a slower speed for a hazard, often a curve or turn. Adjust for road, weather, and traffic, and follow the warning speed.

Handbook p. 115 ↗
Exit speed advisory
Speed warning sign: exit 25 mph

Know the rule

Variable speed limit signs are digital signs that post changing limits to spread out traffic. Advance notification signs can close entire lanes and warn you of slower traffic ahead.

Handbook p. 115 ↗

Know the rule

One Way signs mark streets where traffic flows only in the arrow's direction. Never drive the wrong way on a one-way street.

Handbook p. 115 ↗

Put it into practice

The freeway limit is 60 mph, but thick fog cuts your visibility to a few car lengths. Driving 55 isn't automatically legal: you can be ticketed for going too fast for conditions. Slow down to what's safe.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

The posted speed limit represents the maximum safe speed under what conditions?
  1. Nighttime conditions
  2. Heavy traffic conditions
  3. Ideal conditions
  4. Rainy conditions

Answer: Ideal conditions

The maximum speed limit is for ideal conditions; you must slow further when conditions require it.

Handbook p. 114 ↗
You're driving exactly at the posted speed limit, but the road is icy. Can you still get a ticket?
  1. Only if you're driving at night
  2. Yes, for going too fast for conditions
  3. No, the posted limit is always a safe harbor
  4. No, unless you exceed the limit by 5 mph

Answer: Yes, for going too fast for conditions

Even driving under the posted limit, you can be ticketed for traveling too fast for road conditions.

Handbook p. 114 ↗
Why do some roads post a minimum speed limit?
  1. So slow driving doesn't become a hazard to others
  2. To keep trucks out of the left lane
  3. Because of a state law requiring one on all highways
  4. To reduce fuel consumption

Answer: So slow driving doesn't become a hazard to others

Minimum speed limits require you to travel fast enough that you aren't a hazard to other drivers.

Handbook p. 114 ↗
Which violation can an automated traffic safety camera record you for?
  1. Parking too close to a hydrant
  2. Failing to signal a lane change
  3. Driving with expired tabs
  4. Speeding in a school zone

Answer: Speeding in a school zone

Automated cameras can record you for running a red light, running a railroad signal, or speeding in a school zone.

Handbook p. 115 ↗
A Keep Right sign reminds you to stay in the right lane unless you're passing another vehicle.
  1. True
  2. False

Answer: True

The Keep Right sign reminds drivers to stay right except when passing.

Handbook p. 114 ↗
Variable speed limit signs are meant to do what during changing traffic conditions?
  1. Only apply to commercial trucks
  2. Distribute traffic flow by posting changing speed limits and closing lanes
  3. Fix the speed limit at the highest posted value
  4. Replace all static speed limit signs permanently

Answer: Distribute traffic flow by posting changing speed limits and closing lanes

These digital signs help distribute traffic flow with changing speed limits and can quickly close lanes when needed.
