MOT Pedestrian & Cyclist Safety Measures 3 — Questions and Answers
Question 1: Under ADA regulations, temporary ramps at curb closures in work zones must have a maximum slope of:
- 1:6 (16.7%)
- 1:10 (10%)
- 1:12 (8.3%) (Correct answer)
- 1:20 (5%)
Correct answer: 1:12 (8.3%)
ADA standards require curb ramps and temporary ramps to have a maximum running slope of 1:12 (8.3%) to remain accessible for wheelchair users.
Question 2: A 'share the road' (W16-1P) plaque is used in combination with which primary sign in cyclist-heavy work zones?
- W4-2 (Added Lane)
- W11-15 (Pedestrian) or W11-22 (Bicycle) warning signs (Correct answer)
- R3-17 (No Bicycles)
- W1-1 (Curve)
Correct answer: W11-15 (Pedestrian) or W11-22 (Bicycle) warning signs
The W16-1P 'Share the Road' plaque supplements W11-15 or W11-22 warning signs to remind drivers that cyclists or pedestrians may be using the roadway.
Question 3: In a work zone on a multi-use path, what is the preferred method for separating pedestrian and cyclist traffic?
- Install a jersey barrier between them
- Use painted edge lines only
- Provide physically separated temporary lanes with delineators (Correct answer)
- Post a single sign asking users to be careful
Correct answer: Provide physically separated temporary lanes with delineators
Physical separation with delineators is preferred to reduce conflicts between the faster-moving cyclists and pedestrians sharing a temporary path.
Question 4: When a work zone requires pedestrians to cross an active travel lane, the crossing must be protected by:
- Verbal warnings from workers only
- A flagger or traffic control device at the crossing point (Correct answer)
- Orange paint on the pavement
- Warning lights on nearby equipment only
Correct answer: A flagger or traffic control device at the crossing point
Any unprotected crossing of an active travel lane requires a flagger or an approved traffic control device to stop vehicles and allow safe pedestrian passage.
Question 5: What minimum vertical clearance must a temporary pedestrian overhead canopy or covered walkway provide?
- 6 feet
- 7 feet (Correct answer)
- 8 feet
- 10 feet
Correct answer: 7 feet
Temporary covered walkways adjacent to construction must maintain a minimum vertical clearance of 7 feet to accommodate all pedestrians including those using mobility devices.
Question 6: Which surface condition is unacceptable for a temporary accessible pedestrian route through a work zone?
- Compacted gravel with firm, stable surface
- Asphalt cold patch with smooth finish
- Loose sand or gravel more than 0.5 inches deep (Correct answer)
- Concrete with broom finish
Correct answer: Loose sand or gravel more than 0.5 inches deep
Loose or unstable surfaces make wheelchair travel impossible and violate ADA requirements for accessible routes, which must be firm and stable.
Question 7: What action is required when a school is adjacent to a work zone with heavy pedestrian traffic during school hours?
- Suspend all work during school start and dismissal times
- Coordinate a school crossing guard or flagger at affected crossings (Correct answer)
- Install a temporary traffic signal regardless of warrants
- Notify parents to drive students instead of walking
Correct answer: Coordinate a school crossing guard or flagger at affected crossings
Coordinating a school crossing guard or flagger at crossings near schools during peak pedestrian times is the standard required protective measure.
