Question

Difficulty: HardNavigating Vehicle Blind Spots

On a multi-lane dual carriageway, properly adjusted convex exterior mirrors eliminate vehicle blind spots, making a physical over-the-shoulder check unnecessary prior to changing lanes.

Answer: Answer

Answer

False
Evaluating the statement as False is correct because convex mirrors only widen the angle of reflection and cannot eliminate the blind spots alongside the vehicle body; drivers must always perform a direct physical shoulder check before altering lane position.

Step-by-Step Solution

1
Analyze the optical properties and limitations of convex exterior mirrors.
Convex mirrors produce a wider viewing angle and make vehicles appear smaller and further away, but their reflective field does not wrap around the entire vehicle body.
Understanding mirror geometry identifies the unmonitored areas outside the driver's direct and reflected lines of sight.
2
Determine the zones not covered by interior and exterior mirrors during multi-lane driving.
Vehicles travelling in adjacent lanes slightly behind the driver's peripheral vision remain entirely invisible in all mirrors.
Identifying blind spot locations is necessary to execute safe observational routines before steering or changing speed.
3
Evaluate the procedural requirement for physical shoulder checks under DVSA standards.
A physical glance over the shoulder (lifesaver check) is mandatory to confirm the adjacent lane is clear before changing lanes.
Direct visual checks prevent side-swipe collisions with overtaking traffic, particularly smaller road users such as motorcyclists.
