Why should you reduce speed when approaching roadworks?

101. Why should you reduce speed when approaching roadworks?

✓ Road workers, narrow lanes, and unexpected hazards may be present.
To reduce wear on the vehicle suspension.
To keep construction dust off the windscreen.
To reduce exhaust gases near construction sites.

Roadworks can involve workers, machinery, changing lane layouts, and uneven surfaces. Lower speed gives you more time to react.
