Intersections are any place traffic merges or crosses: cross streets, side streets, driveways, and shopping center or parking lot entrances. They're where paths cross, so they need your most careful scanning.

Before and while entering an intersection:

  • Look left and right for vehicles and pedestrians
  • If stopped, look left and right again just before you move
  • Look across to be sure the path is clear all the way through and you won't block it
Handbook p. 19 ↗

Before turning left across traffic:

  • Look for a safe gap in oncoming traffic
  • Check the street you're turning into for vehicles or pedestrians
  • Look once more at oncoming traffic before you turn
Handbook p. 19 ↗

Know the rule

Before turning right, make sure no traffic is approaching from your left, no oncoming vehicle is turning left into your path, and no pedestrians are crossing where you'll turn.

Handbook p. 19 ↗

Know the rule

You may turn right on red unless prohibited, and turn left from a one-way street into another one-way street unless prohibited.

Handbook p. 19 ↗

Know the rule

Don't rely on signals or signs to keep others from crossing. Look left and right even if cross traffic has a red light or stop sign, especially just after your light turns green.

Handbook p. 19 ↗

Know the rule

If your view of a cross street is blocked, edge forward slowly until you can see; crossing drivers see your front bumper first and can warn you.

Handbook p. 19 ↗

Know the rule

Look to the sides near shopping centers, parking lots, construction areas, busy sidewalks, playgrounds and schoolyards.

Handbook p. 19 ↗

Know the rule

At any railroad crossing, slow down and look up and down the tracks. Never assume no train is coming, even if you've never seen one there; that assumption is a leading cause of crossing deaths.

Handbook p. 19 ↗

Know the rule

With more than one track, wait until the passing train is well down the track before crossing; another train may be hidden behind it.

Handbook p. 19 ↗

Put it into practice

Your light just turned green. Before pulling out, you glance left and right and see a driver racing to beat the red on the cross street. You wait, and avoid a T-bone crash.

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.

According to the handbook, what is one of the leading causes of fatalities at railroad crossings?
  1. Stalling after shifting gears
  2. Assuming that a train is not coming
  3. Stopping too close to the gate
  4. Crossing the tracks too slowly

Answer: Assuming that a train is not coming

Assuming that a train is not coming is one of the leading causes of fatalities at railroad crossings.

Handbook p. 19 ↗
Before entering an intersection, what should you do?
  1. Look left and right for traffic
  2. Watch only the traffic signal
  3. Only look in the direction you plan to turn
  4. Only check your rearview mirror

Answer: Look left and right for traffic

Before you enter an intersection, look to both the left and right for approaching vehicles and crossing pedestrians.

Handbook p. 19 ↗
Why is it especially important to look left and right just after a light turns green?
  1. The signal may still be yellow for cross traffic
  2. Oncoming drivers must yield to you then
  3. Pedestrians are not allowed to cross at that moment
  4. Cross traffic may rush to beat the red light

Answer: Cross traffic may rush to beat the red light

This is when drivers on the cross street are most likely to hurry through before their light changes to red.

Handbook p. 19 ↗
At a railroad crossing with more than one track, why should you wait after the first train passes?
  1. A second train may be hidden
  2. The signal lights need time to reset
  3. The rails stay slippery for a while
  4. The gate may lower again at once

Answer: A second train may be hidden

Wait until the passing train is well down the track — another train could be hidden by the one that just passed.
