Driving by Road Class
This isn't trivia — everything in this lesson should change your behaviour depending on where you are:
On Class A/B roads with long straight sections and high speed limits, your main hazard is usually other motorised traffic — overtaking lorries, matatus stopping unpredictably to pick up passengers. Speed differential between vehicle types is your biggest risk.
On Class D/E rural roads, slow down your assumptions, not just your speed. Expect livestock, unlit non-motorised traffic especially near dusk, poor or absent road markings, and surfaces that change grip suddenly — murram to mud in rain. This is where you'll share space with the most vulnerable road users in the least protected conditions, and where the burden of vigilance sits most heavily with you.
On controlled-access roads (expressways), check signage before assuming any road user might be present — but never assume the road is "cleaner" of hazards just because pedestrians and boda bodas are banned. High speed means any incident — a breakdown, debris, an animal that has somehow entered — is far more dangerous, not less.
The one-line version of this whole lesson: let road class set your hazard expectations, not just the speed limit. Two roads with the same limit can demand completely different driving.
Key takeaways
- Class A/B: the risk is speed differential between vehicle types · Class D/E: the risk is vulnerable users, animals and changing surfaces · Expressways: fewer user types, but every incident is amplified by speed
- Same speed limit, different road class = different driving
Quick check
Two roads both carry a 50 km/h limit: a Class B road through a town, and a Class E murram road past a market. What changes between them?
