What's the purpose of road humps, chicanes and narrowings?
- A To separate lanes of traffic
- B To increase traffic speed
- C To allow pedestrians to cross
- D To reduce traffic speed
Why this is the answer
Traffic-calming measures help to keep vehicle speeds low in congested areas where there are pedestrians and children. A pedestrian is much more likely to survive a collision with a vehicle travelling at 20 mph than they are with a vehicle travelling at 40 mph.
Why the other answers don't fit
- A
- To separate lanes of traffic — Lanes are separated by road markings.
- B
- To increase traffic speed — Precisely the opposite of their purpose.
- C
- To allow pedestrians to cross — Crossings are provided separately, though calming certainly helps at them.
