Making Turns At Multi-Lane Intersections

Making Turns on Multi-lane Roads Safely | Driving Like A Pro

Updated May 6, 2019

Making turns at intersections on multi-lane roads is a little more complicated than it is at dual-lane intersections. On a standard intersection, the general rule for executing turns is as follows:

  • Right turns should begin and end in the furthest lane to the right
  • Left turns should begin and end in the furthest lane to the left

Multi-lane intersections often have additional lanes or dedicated “turn lanes” for motorists wishing to turn, in which case, the general rules outlined above may no longer apply. When preparing to make any turn from a multi-lane road, drivers must:

  • Identify which lane or lanes they may use to turn, as they approach the intersection.
  • Merge into the correct lane and activate their turns signal at least 100 feet before the turn – even if you are in a protected turn lane. Some state handbooks may specify other distances, so be sure to check yours out.
  • Proceed with caution if their view around the intersection is obscured.

The risk of conflict with other motorists when turning from one multi-lane road onto another multi-lane road is high. You can mitigate this risk by yielding to all other traffic crossing the intersection before executing the turn.

In addition, be sure to finish the turn in the lane which corresponds to the lane you started in. For example: when beginning a turn in the third lane from the right on one street, you should end up in the third lane from the right on the new street. Never attempt to switch lanes while part-way through an intersection.

Staggering your vehicle in relation to cars in adjacent lanes will reduce the chances of a collision occurring. Turning while directly alongside another vehicle is risky, as your paths of travel may conflict.

Turning left on a multi-lane roadway

Turning left on a multi-lane road presents additional dangers and challenges, as it requires you to cross multiple lanes of conflicting traffic. Many intersections have brief lanes dedicated to left turns, sometimes known as “left turn bays”. These lanes are designed to maintain traffic flow through the intersection and protect motorists wishing to make a left turn.

When no such dedicated turn lanes are available, you may have to contend with relentless streams of opposing traffic while attempting to make a left turn. Do not rush to complete the turn or panic if the signal lights change while you are still on the intersection. A vehicle part-way through making a left turn is permitted to sit on the intersection even after signals have changed, for as long as it takes to safely complete the maneuver.

You must come to a complete stop and leave your wheels pointing straight ahead, until all traffic has cleared the intersection. Eventually, cross traffic will be halted by a red or yellow signal light and you will be able to finish the left turn.

Driving on Highways 1 of 10

Driving on Highways

Highways are the backbone of the United States transportation system. Together, they connect every major population in the country. These high-speed, limited-access roads make it possible to travel long distances conveniently and safely - providing you abide by the rules and avoid taking unnecessary risks.

Understanding Highways

Highways are usually the best roads to use when traveling long distance. These roads are also known as expressways, limited access highways, interstate highways, turn pikes, toll roads and freeways. Freeways are only our country’s safest roads when you know how to drive on them correctly. When traveling at high speed, amidst large volumes of traffic, enormous trucks and ever-changing conditions, motorists must be at the top of their driving game.

Highway Driving Approaches

Despite occurring far less frequently, collisions on highways are usually more severe than collisions on other roads. When high speeds are involved, the chances of a collision resulting in fatalities are much greater. Making a mistake on a highway could cost you your life.

Driving on Curves & Hills 1 of 3

Curves and Hills

When driving through a stretch of road that is not flat, or straight, a motorist must contend with additional forces acting on their vehicle. Adjustments in speed and lane position must be made to counteract these forces and maintain control. Furthermore, line of sight may be impeded by the mid-point of a curve or the crest of a hill.

Driving Through Curves

You do not need to be a rocket scientist to navigate curves in the road safely, though you will need to understand the forces acting on your vehicle and learn how to maintain control. When driving through any curve in the road, the circular pathway of your vehicle will create a centrifugal force which pulls it toward the outside edge of the curve. Always be on the lookout for curves in the road ahead of you and make any necessary speed and position changes as soon as possible.

Driving on Hills

Driving on hills presents many of the same challenges as driving on a curved road. Your ability to see opposing traffic may be impeded by the crest of the hill and additional forces will be acting on your vehicle. Whereas centripetal and centrifugal forces will affect your car while driving through a curve, hill driving means you must contend with gravity. The steeper the hill, the greater this effect will be.

Driving in Heavy Traffic

Heavy traffic is a major contributing factor to many complex risk environments, such as limited access highways, urban areas, complex intersections and multi-lane roads. When sharing the roadway with a large volume of other motorists, drivers must be able to multitask. While monitoring the area around your vehicle, you will also need to scan the road ahead, position your vehicle appropriately, maintain a safe speed and ensure you are in the correct lane.

Heavy Traffic at Intersections

The risk of being involved in a collision is considerable at intersections – particularly during rush hour and other times when traffic is heavy. Recent collision data indicates that around 47 percent of all crashes occur at intersections – including roughly half of all crashes which result in injury.

Heavy Traffic on Multi-lane Roads

Driving on busy, multi-lane roads requires constant vigilance. With traffic and potential hazards in-front, behind and on both sides of your vehicle, the risk of an accident or collision occurring is high. At a moment’s notice, you must be ready to alter your speed or lane position to avoid danger.
