What are Passing and Overtaking Rules?

Passing and overtaking rules regulate when, where, and how drivers may pass a vehicle ahead. These rules are designed to prevent head-on collisions and ensure that overtaking maneuvers are safe. Violations carry significant fines and can result in serious accidents.

Short answer

Passing is prohibited over solid double lines, near curves, intersections, hills, and crests. Safe overtaking requires 100+ meters of clear visibility ahead, proper signaling, and ensuring no oncoming traffic is within safe distance.

Safe Overtaking Procedure

1
Check Ahead
Ensure 100+ meters of clear visibility and no oncoming traffic
↓
2
Signal
Use left turn signal to indicate overtaking intent
↓
3
Accelerate
Build sufficient speed to complete pass safely
↓
4
Return to Lane
Complete pass with safe distance before the vehicle ahead
↓
5
Signal Right
Turn off left signal and reestablish normal spacing

Step-by-step worked examples

You approach a car on a two-lane road. You see a solid double line. Can you pass?

Solid double line = no passing zone
Answer: No — passing is strictly prohibited over solid lines.

A curve is ahead and the road is clear. Is it safe to overtake?

Curves reduce visibility and control
Answer: No — never pass on curves or hills; reduced visibility = collision risk.

You have 150 meters of clear visibility ahead. Can you safely overtake?

Safe overtaking requires 100+ meters visibility (this is 150, sufficient)
But also check: no solid line, no intersection, straight road ahead
Answer: Only if all other conditions are met.

Common mistakes

✗

Passing when visibility is 80 meters (thinking it's 'close enough'). — Correct: Always ensure 100+ meters of clear road; 80 m = insufficient margin.

✗

Believing you can pass on a hill or curve if no car is visible. — Correct: Visibility is obscured on hills/curves — oncoming traffic may be hidden.

✗

Ignoring solid double lines because the road 'looks empty.' — Correct: Solid lines legally prohibit passing regardless of current road conditions.

✗

Thinking dashed lines allow passing in both directions. — Correct: Dashed lines are typically from one direction only; check your side.

FAQ

What is the fundamental rule of passing and overtaking?

Only pass when visibility is clear, no solid lines prohibit it, and you can safely complete the maneuver.

Are there different rules for passing on highways vs. local roads?

Core rules apply everywhere, but some highways may have additional restrictions in certain zones.

What do I do if an oncoming car suddenly appears while I'm overtaking?

Brake firmly, return to your lane, and do not attempt to complete the pass.

Can I exceed the speed limit while overtaking to pass quickly?

No — maintain legal speed. Speeding while passing increases crash risk and is illegal.
