Situations When Passing Is Illegal

How To Avoid Illegal Passing Situations & Dodge That Ticket (w/ Pictures)

Updated Nov. 16, 2020

Like most rules of the road, the rules concerning passing may have slight differences from one state to the next. However, the general situations in which passing is illegal apply across America – and in most other western countries. You must learn when passing another vehicle is prohibited, as this knowledge will be assessed during the theory and practical driving tests.

Qualified drivers must also keep up-to-date with passing rules and restrictions, as making an illegal pass could earn you a ticket and create a dangerous driving situation. Do not pass another vehicle under any of the conditions listed below.

When is passing illegal?

While these are the most common situations in which passing another vehicle is prohibited, be sure to consult your driving handbook for state-specific information, in addition to memorizing these general rules.

Passing is illegal when:

  1. 1

    A curve in the road limits your view.
    You must be able to see that the road is clear for at least 800 feet in the opposing traffic lane. This will not be possible when the road curves sharply.

  2. 2

    There is a hill up ahead.
    When approaching a hill, vehicles traveling towards you in the opposite lane may be hidden.

  3. 3

    Weather conditions restrict your line of sight.
    Visibility will be too low to pass safely in snowy, rainy or foggy conditions. Unfavorable weather makes driving hazardous enough, without adding low-visibility passing to the mix. In most states, passing in these conditions is illegal. Check out our hazardous condition articles to learn more about driving safely in these situations.

  4. 4

    You are passing through an intersection, or are within 100 feet of an intersection.
    The precise distance from an intersection at which passing is prohibited may differ slightly from this in your state. Though it is best to play is safe and use “not within 100 feet” as your rule.

  5. 5

    You are less than 100 feet away from a tunnel or bridge.
    Passing is not safe as the road may narrow up ahead. Legal distances may vary slightly in your state.

  6. 6

    You are less than 100 feet away from a railroad crossing.
    Legal distances may vary slightly in your state.

  7. 7

    You are using a center turn lane or passing would require you to enter the center turn lane.
    These lanes may only be used to make a left turn, or to enter the road from a driveway or alley. Passing in a center turn lane is illegal.

  8. 8

    The road is marked with “DO NOT PASS” or “NO PASSING ZONE” signs.

  9. 9

    Road markings forbid passing on this stretch of road.
    These markings may be used alongside road signs. Passing is generally prohibited when there is an unbroken dividing line between lanes, on your side of the divide.

  10. 10

    A school bus displaying red flashing lights or a “STOP” arm has stopped ahead of you.
    In this situation, you should stop 20 feet away from the bus until it moves off. Never attempt to pass a stopped school bus.

  11. 11

    You would be passing on the right side of the vehicle in front.
    There are some circumstances in which passing on the right is permitted but it is usually illegal, in most states. Check your state’s own driving handbook for details.

  12. 12

    The vehicle you intend to pass is turning left.
    If you attempt to pass at the same time, a collision is almost guaranteed.

  13. 13

    There are more than two lanes of traffic traveling in your direction and the vehicle you hope to pass is using the left-hand lane.

These rules should be relatively easy to remember, as they are largely common-sense restrictions. If passing another vehicle would put you or another road user in danger, it is probably illegal. As we mentioned above, be sure to check your state driver handbook for local rules and restrictions which may not be listed here.

Parking Your Car Like A Pro
Parking 1 of 8


When learning to drive, you must learn how to angle park, perpendicular park and parallel park. The latter of these three techniques – along with parking on a hill – is almost guaranteed to come up during your practical driving exam. Attempting to park becomes dangerous if you fail to think ahead or allow yourself to get stressed-out by other drivers.

Parking Restrictions

Parking Restrictions

Parking is illegal or restricted in many areas. Unfortunately, you cannot always rely on colored curb markings or a “NO PARKING” sign being present in places where parking is prohibited. As a driver, it is your responsibility to learn about parking rules, restrictions and prohibitions and abide by this information at all times.

Angle Parking
Parking 3 of 8

Angle Parking

Angled parking spaces are designed to make parking easy. This maneuver is far less challenging than parallel parking or perpendicular parking but will still take a little practice to get right. Angled parking spaces are painted with the same dimensions pretty much across the whole of America: once you’ve mastered angle parking, you should be able to repeat the maneuver with ease anywhere.

Center Turn Lane

Center left turn lanes are also referred to as two-way left turn lanes. These lanes are designed to improve the flow of traffic at busy intersections, by allowing drivers to safely turn left without interfering with motorists traveling straight on. You may use the two-way left turn lane when turning left onto the roadway from an alley or driveway.

Making Turns 7 of 9

Two Point Turns

When the roadway is not wide enough to make a U-turn, drivers can use a two-point turn to change direction. This will usually only be possible on quiet suburban streets, when there is an available driveway on the left or right side of the road to facilitate the turn. Two-point turns using driveways on the left are more dangerous, as the driver must reverse the vehicle into a traffic lane.

Making Turns 8 of 9

Three Point Turn

Three-point turns are more complex than two-point turns and U-turns. You must know how to execute a safe three-point turn, as they are a standard point of assessment on practical driving tests state-wide. If you need to reverse your direction of travel on a street that is too narrow for a U-turn and has no driveways to allow a two-point turn, making a three-point turn will be your only option.

Making Turns 9 of 9


Making a U-turn is the quickest and easiest way to turn your vehicle around should you need to reverse your direction of travel. This may happen if you find you are traveling in the wrong direction or if you accidentally over-shoot your destination.

Passing Basics

Passing another vehicle immediately puts you and every road user around you at risk, no matter how safely you execute the maneuver. Passing-related collisions are often high-speed and head-on, which sadly means they are usually fatal. All drivers must learn how and where they should pass other vehicles, in addition to situations in which passing is forbidden.

Passing: Step-by-Step

When learning to pass another vehicle, the most important skill that new drivers must develop is accurately judging whether there is enough space to pass safely. Overestimating how much room you have could cause a serious collision. When passing at highway speeds, drivers need a 10 to 12 second gap in opposing traffic to execute the maneuver safely. During this gap, you will travel approximately 800 feet, or one third of a mile.
