MOT Pedestrian & Cyclist Safety Measures 4 — Questions and Answers
Question 1: On a high-speed roadway (posted 55 mph), what is the recommended minimum advance warning distance for a pedestrian work zone sign?
- 100 feet
- 350 feet
- 500 feet (Correct answer)
- 1,000 feet
Correct answer: 500 feet
MUTCD Table 6C-1 recommends 500 feet of advance warning distance for work zones on roads posted at 55 mph to give drivers adequate reaction time.
Question 2: Longitudinal channelizing devices along a temporary pedestrian path should be placed at a maximum spacing of:
- 5 feet
- 10 feet (Correct answer)
- 25 feet
- 50 feet
Correct answer: 10 feet
Devices defining a temporary pedestrian path should be spaced no more than 10 feet apart to provide continuous visual guidance along the route.
Question 3: A contractor plans to close a sidewalk for 6 months. What type of temporary pedestrian facility is typically required?
- Simple rope barrier with signs
- Scaffolded covered walkway with full enclosure (Correct answer)
- Yellow caution tape only
- Reduce the work zone to avoid the closure
Correct answer: Scaffolded covered walkway with full enclosure
Long-term sidewalk closures (months) generally require a fully enclosed, scaffolded covered walkway to protect pedestrians from overhead construction hazards.
Question 4: When installing temporary rumble strips to alert drivers to a work zone, they must NOT be placed:
- Before the taper
- In a bicycle lane without a bypass route for cyclists (Correct answer)
- On a two-lane road
- At night
Correct answer: In a bicycle lane without a bypass route for cyclists
Rumble strips in a bike lane create a serious hazard for cyclists and must not be installed there unless a safe alternate route for cyclists is provided.
Question 5: What is the primary purpose of a channelizing fence (Type C barricade) along a temporary pedestrian route in a work zone?
- Prevent vehicles from entering the work area
- Provide a continuous physical barrier guiding pedestrians safely past the work zone (Correct answer)
- Display regulatory speed limit signs
- Mark the edge of the excavation for workers
Correct answer: Provide a continuous physical barrier guiding pedestrians safely past the work zone
Type C barricades serve as continuous physical channelizers that guide pedestrians safely along the designated path and away from the work zone.
Question 6: Which of the following is a required element of a Temporary Traffic Control (TTC) plan for a work zone affecting cyclists?
- Approval from all adjacent cyclists by petition
- Identification of alternate bike routes and appropriate signage (Correct answer)
- Installation of permanent bike infrastructure
- Reduction of the posted speed limit to 15 mph
Correct answer: Identification of alternate bike routes and appropriate signage
A TTC plan affecting cyclists must identify and sign alternate routes so cyclists are safely directed around the work zone without using the closed lane.
Question 7: High-visibility safety vests worn by flaggers near pedestrian pathways must meet what minimum ANSI/ISEA classification?
- Class 1
- Class 2 (Correct answer)
- Class 3
- Class E
Correct answer: Class 2
Flaggers must wear at minimum ANSI/ISEA Class 2 high-visibility garments, which provide greater background material and reflective striping than Class 1.
