Michigan DMV Permit Test: Warning, School, Railroad, and Work Zone Signs Concepts

Importance ★★★★★ · 40% (estimate)

Overview

Warning signs tell you about a hazard or a change in the road ahead. Most are yellow diamonds with black letters or symbols, because the diamond shape means warning and yellow means caution. Other colors add detail: orange is for construction and maintenance, fluorescent yellow-green is for schools, pedestrians, and bicycles, and fluorescent pink marks an incident or emergency.

Railroad crossings have their own signs. The round yellow advance warning sign tells you a crossing is ahead, and the white crossbuck stands at the tracks. If a train is coming, stop between the distances given below, because trains overhang the rails. A crossing with a STOP sign requires a stop even when no train is in sight.

Work zones are marked with orange signs and may lower the speed limit while workers are present. Fines for moving violations are doubled there and speeding adds more points. Construction workers may direct traffic, and you must follow them even when a signal says otherwise. The pentagon marks a school area, and the yellow pennant on the left side of the road warns of a no-passing zone.

Key concepts

  • Warning sign

    Usually a yellow diamond with black letters or symbols. It warns of a hazard or change ahead, such as a curve, a merge, a lane ending, or a deer crossing.

    Memory tipDiamond means: something is coming up, be ready.

  • Railroad advance warning

    The round yellow sign warns that a railroad crossing is ahead. If a train is coming, stop no more than 50 feet and no less than 15 feet from the tracks.

    Memory tipRound sign: slow down, look and listen for trains.

  • Crossbuck

    The white X-shaped sign that marks the railroad crossing itself. At passive crossings it may come with a YIELD or STOP sign, and there are no lights or gates.

    Memory tipCrossbuck at the tracks; round sign before them.

  • Work zone signs

    Orange diamond signs mark construction and maintenance areas. The speed limit is often 45 mph when workers are present, and fines for moving violations are doubled.

    Memory tipOrange: slow down and watch for workers.

  • School pentagon

    The five-sided fluorescent yellow-green sign marks a school area or crossing. Drive carefully, watch for children, and obey a school crossing guard.

    Memory tipFive sides: think school children.

  • No-passing pennant

    A yellow pennant-shaped sign placed on the left side of the road. It warns that conditions make passing hazardous.

    Memory tipThe pennant faces the passing lane side.

  • Slow-moving vehicle emblem

    An orange triangle on the back of vehicles that cannot go faster than 25 mph, such as farm machinery and horse-drawn buggies.

    Memory tipOrange triangle: expect a very slow vehicle.

See it in a picture

Six labeled warning shapes: a yellow diamond for general warning, an orange diamond for construction, a yellow-green pentagon for school, pedestrian, and bicycle, a pink diamond for incidents, a round yellow sign with an X (railroad ahead), and an orange triangle with red border (slow vehicle).
The color of a warning sign tells you what kind of hazard to expect.

Often tested

  • Most warning signs are yellow diamonds; orange ones mark work zones.
  • Yellow-green is for school, pedestrian, and bicycle cautions; pink is for incidents.
  • When a train is coming, stop 15 to 50 feet from the tracks.
  • Always stop at a crossing with a STOP sign, even if no train is in sight.
  • Follow a construction worker's directions even if the signal says otherwise.
  • When your lane ends, merge and yield to traffic in the other lane.

3 sample questions

Verified practice questions from this unit.

Practice questionReviewedRoad Signs › Warning, School, Railroad, and Work Zone Signs★★★★★

Question 1. What does this sign warn you about?

A round yellow sign with a black border. A large black X crosses the whole sign, and a black capital letter R sits in the left space and in the right space between the arms of the X.
  1. ① Railroad tracks run beside the road, with no crossing
  2. ② The road is closed ahead
  3. ③ An intersection with a four-way stop is ahead
  4. ④ A railroad crossing is ahead
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ④ A railroad crossing is ahead

Key point: Round yellow sign with X and two Rs: railroad crossing ahead

The only round sign is the railroad advance warning sign. It warns that a railroad crossing is ahead. Slow down, look and listen for trains, and be ready to stop.

Wrong choices

  • Railroad tracks run beside the road, with no crossing: This sign warns that you will cross tracks ahead.
  • The road is closed ahead: Road closures do not use this round sign.
  • An intersection with a four-way stop is ahead: An intersection warning is a yellow diamond. The round yellow sign is used only for railroads.

Question 2. What does this five-sided sign tell you?

A five-sided sign shaped like a house with a pointed top. It is fluorescent yellow-green with a black border and shows black figures of two children walking.
  1. ① A bus stop is ahead
  2. ② A hiking trail crosses ahead
  3. ③ You are near a school or school crossing; watch for children
  4. ④ Pedestrians are not allowed on this road
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ You are near a school or school crossing; watch for children

Key point: Pentagon (five sides): school area or crossing

The pentagon shape is used for school signs, and fluorescent yellow-green is the color for school, pedestrian, and bicycle cautions. Drive carefully, watch for children, and obey any school crossing guard.

Wrong choices

  • A bus stop is ahead: Bus stops are not shown with this five-sided sign.
  • A hiking trail crosses ahead: Recreation signs are brown.
  • Pedestrians are not allowed on this road: A ban would use a red circle and slash, not a yellow-green pentagon.

Question 3. Most warning signs have which shape and color?

  1. ① A yellow diamond with black letters or symbols
  2. ② A red octagon with white letters
  3. ③ A green rectangle with white letters
  4. ④ A white rectangle with black letters
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ① A yellow diamond with black letters or symbols

Key point: Warning signs: mostly yellow diamonds

The diamond shape means warning, and yellow means caution or general warning. These signs tell you about a hazard or change ahead, such as a curve, a merge, or a crossing.

Wrong choices

  • A red octagon with white letters: That is the STOP sign.
  • A green rectangle with white letters: That is a guide sign giving directions.
  • A white rectangle with black letters: That is the usual look of a regulatory (rule) sign.
