Is it okay to drive in the right hand lane if there isn't a keep left unless overtaking sign?
Well, no, that's not the rule.
If the speed limit on a multi-lane road is 90 kilometres per hour or more, there's no need for a keep left unless overtaking sign.
You must keep the right hand lane free, unless:
- you are overtaking
- avoiding an obstruction
- or if the traffic in the left hand lanes is congested.
It's all about keeping the traffic moving.
So remember the rule, if the speed limit is 90 kilometres per hour or more, you must keep left so the right lane is always free
