KSRTC Thiruvalla – Bangalore Super Deluxe Overtaking TN’s SETC Deluxe Bus
Overtaking or passing is the act of one vehicle going past another slower moving vehicle, travelling in the same direction, on a road. The lane used for overtaking another vehicle is almost always a passing lane further from the road shoulder which is to the left in places that drive on the right and to the right in places that drive on the left.
On a single-carriageway/undivided-carriageway road, the lane used for overtaking is often the same lane that is used by oncoming traffic, and it is often only advisable to overtake on long straightaways with plenty of visibility. In some jurisdictions, the “overtaking zone” is indicated by a single broken center line (yellow or white in most countries) if overtaking is allowed in either direction, or paired with a single solid line beside it to indicate there is no overtaking from the solid side. In the UK, the format of the centerline is not used to regulate overtaking, only to indicate whether crossing of the line is prohibited or permitted.
