You’re checking your vehicle before a long night-time motorway journey in heavy rain. Which of the following actions will best help you make safe use of reflective road studs alongside white lines, as described in the Highway Code?

Explanation

Highway Code Rule 132 states that reflective road studs may be used with white lines to improve visibility, particularly at night or in poor weather. To make effective and safe use of them, you must be able to see them clearly. Good vehicle maintenance is essential: clean and correctly aimed headlights, a clean windscreen inside and out, and clean prescription glasses (if worn) all improve your ability to see reflective studs and lane markings in the dark and in rain. Lowering tyre pressures (option B) is unsafe and does not improve visibility. Using rear fog lights unnecessarily (option C) can dazzle other drivers and is only appropriate in seriously reduced visibility. Relying mainly on a sat nav (option D) instead of observing the road, studs and white lines is unsafe and contrary to the Highway Code’s requirement to use road markings and signs to guide your driving.
