You must not apply sudden braking except when unavoidable to avoid danger.

[True / False · Easy]

Answer: ✓ True

Explanation

Chapter 5, Section 4, 3(3) of the Rules of the Road clearly states that you must not apply sudden braking except when unavoidable to avoid danger. This is because sudden braking can cause dangers such as rear-end collisions with following vehicles.

Wait, I thought sudden braking was always bad. Shouldn't it say 'never'?

Misaki

This statement is true. You must not apply sudden braking except when it's unavoidable to avoid danger — that exception is key.

Hikari

So there are times when you have to slam the brakes?

Misaki

Correct. If it's the only way to prevent a collision, sudden braking is allowed. Otherwise, it risks rear-end collisions.
