The second group of warning signs shows what the road does next, such as curves, intersections and crossings, and who else might be using it.

Pedestrian crossing
Pedestrian Crossing

Someone may be crossing:

  • Pedestrian Crossing: be alert; slow down, yield to pedestrians, stop if necessary
  • School Advance Crossing: a crosswalk where school children cross is ahead
  • School Crossing: at the crossing itself; obey school crossing guards
  • Bicycle: be alert for bicyclists crossing the street

Curves:

  • Reverse Turn: the road turns sharply right, then left (may be shown either way)
  • Reverse Curve: the road curves right, then left (may be shown either way)
  • Curve: a gradual curve ahead; slow to the safe speed indicated
  • Advisory Speed Plaque: added under a diamond sign to show the advisory speed for the condition

Intersections and merges:

  • Winding Road: a series of turns or curves ahead
  • Crossroad: a four-way intersection ahead; watch for cross traffic
  • T Intersection: the road ends ahead; signal before turning right or left
  • Sideroad: a road joins from the right; watch for entering vehicles
  • Traffic Merging From Right: adjust speed and lane position so traffic can merge safely

Roundabout ahead
Roundabout ahead

Know the rule

Roundabout sign: slow down and YIELD at the roundabout, to all vehicles approaching on your left already in it.

Handbook p. 49 ↗
Railroad crossing ahead
Railroad Crossing advance warning

Know the rule

The round Railroad Crossing sign warns of a crossing ahead: yield, and be prepared to stop if a train is approaching. A No Train Horn sign beneath it marks a quiet zone where trains don't blow the horn.

Put it into practice

A yellow diamond shows a T. The road you're on ends ahead, so slow down, signal, and turn right or left when it's clear.

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.

A 'Crossroad' warning sign means a road joins from the right only.
  1. True
  2. False

Answer: False

The Crossroad sign means a four-way intersection is ahead; a road joining only from the right is shown by the Sideroad sign.

Handbook p. 49 ↗
A yellow diamond warning sign showing arrows chasing each other in a circle means:
  1. A U-turn area is ahead; prepare to stop
  2. Traffic merges from both sides ahead
  3. A detour around road work is ahead
  4. A roundabout is ahead; slow down and yield

Answer: A roundabout is ahead; slow down and yield

The roundabout sign warns of a roundabout ahead: slow down and yield to vehicles already in it on your left.

Handbook p. 49 ↗
A yellow diamond warning sign showing a 'T' means:
  1. Your road ends ahead; signal to turn
  2. A side road joins from the right ahead
  3. A four-way crossroad intersection is ahead
  4. Two-way traffic begins on the road ahead

Answer: Your road ends ahead; signal to turn

The T Intersection sign means the roadway ends ahead and you must signal before turning right or left.

Handbook p. 49 ↗
An Advisory Speed Plaque is used to:
  1. Set a new legal maximum speed for the zone
  2. Add an advisory speed to a warning sign
  3. Mark the minimum speed allowed on the interstate
  4. Show the speed limit when children are present

Answer: Add an advisory speed to a warning sign

The plaque supplements a warning (diamond) sign to show the advisory speed for that condition.

Handbook p. 48 ↗
A 'No Train Horn' sign under a railroad crossing sign means trains do not blow their horns at that crossing.
  1. True
  2. False

Answer: True

No Train Horn signs are installed where a quiet zone has been established; trains do not blow the horn there.
