What is the standard reference point for 3-6 inches away from a line on the right as illustrated?

As a new driver, you may have trouble making traffic maneuvers that are smooth and more accurate such as parallel parking in a correct distance to the curb or making smooth turns. This is because you cannot accurately see where your car is positioned on the road or next to the curb.

In order to get a better idea as to where your car is positioned compared to the curb, pavement lines or road's marking, you need to set a few reference points on your car such as the center of your hood and draw a straight line with your eyes (line of sight) to a pavement line or curb.

There are common (standard) reference points on a vehicle that you can use; however, these reference points are just approximate. This is because these common (standard) reference points were calculated based on a sedan automobile and a person of a standard height.

In order to get an accurate idea of your car's reference points compare to a pavement line or curb, you should take your car to an empty parking lot and set up your own reference points based on comparing those reference points to the curbs and pavement lines.

Examples of common reference points:

Your hood - You can divide your car's hood into these reference points:
Left Corner, 1 Foot from Left Corner, Center Left, Center of Hood, Center Right, 1 Foot from Right Corner, Right Corner.

Examples of measuring your car's distance from the right curb or right pavement line:

  • If you can draw a straight line with your eyes from the center of your car's hood to the right curb or right line, then your vehicle is about 3-6 inches away from the right curb or right line.
  • If you can draw a straight line with your eyes from the center right of your car's hood to the right curb or right line, then your vehicle is about 3 feet away from the right curb or right line.

Example of measuring your car's distance from the left curb or left pavement line:

  • If you can draw a straight line with your eyes 1 foot from the left corner of your car's hood to the curb to the left, then your vehicle is about 3-6 inches away from the left curb or left line.

Example of measuring your car's front bumper distance from an intersection line:

  • If you can draw a straight line with your eyes from your passenger's side mirror to the intersection line or the curb, your front bumper is right at the intersection line.

Example of measuring your car's rear bumper distance from the rear pavement line:

  • If you look over your left shoulder and you can draw a straight line from the middle of the back seat's left-side window to the rear pavement line, your rear bumper is about 3-6 inches away from the rear pavement line.

One of your biggest challenges as a new driver will be learning to identify where your vehicle sits in relation to the roadway. Developing this sense is essential, as it will make sure you can correctly position yourself within a lane and avoid colliding with the curb, other vehicles and obstacles. Correctly estimating your vehicle’s location is extremely hard, as your view from the driver’s seat will be impeded by the hood, dashboard and trunk. Reference points are the key to positioning and maneuvering your car accurately. Master these visual guides and challenging maneuvers like parallel parking will soon be a walk in the park.

When learning about car reference points it is important to remember that standard reference points are only ever approximations. Vehicles come in all shapes and sizes and as such, will have slightly different optimal reference points. Your car may be longer, shorter or wider than the vehicle used in these examples. Keep this in mind and adjust your reference points as necessary while practicing driving maneuvers. If the reference points are different, it is likely they will only be slightly off the mark.

Side position reference points are used to locate a vehicle in relation to side-adjacent road markings and obstacles, like the curb or another parked car. These points of reference will help whenever you are trying to park or position yourself within a lane.

Your vehicle’s left headlight makes for an excellent reference point when attempting to park on the left side of the road. Take advantage of this reference point by imagining a line through the point where the left fender meets the hood. This point should line up with adjacent lane markings or the curb when you are three to six inches away, which is the distance you should aim for when parking or assuming lane position two.

To summarize, your left headlight should be used for reference when you need to do any of the following:

  • Park next to the curb on the left side of the roadway
  • Position the vehicle in preparation for a left turn
  • Drive in lane position two

Center of the hood

When positioning yourself in relation to the right curb, use the center of your hood as a point of reference. This should allow you to maneuver very close to the right curb without hitting it. Generally, when the curb appears to intersect the middle of the hood from your viewpoint in the driver’s seat, your vehicle is in the ideal position, three to six inches away from it.

The center of the hood should be your reference point when trying to:

  • Park the vehicle on the right side of the roadway
  • Position the vehicle in preparation for a right turn
  • Drive in lane position three

Reference points for the “STOP” line

You must be able to determine how close the front of your vehicle is to a stop line, once the line itself has been obscured by the hood. Drivers must stop as near to the line as possible, without the front bumper or any other part of the vehicle actually going over the line. Your side-view mirrors provide the best reference points to use in this situation. The image shows how a stop line would look in relation to your left side-view mirror, when your vehicle stops just before the line.

Here is how the stop line would look beside your right side-view mirror when the vehicle has stopped just before the line. If you are standing in the right lane, the stop line will not be visible from the right side window.

Rear end of the vehicle

When it comes to reversing and parallel parking, you must know the rear limit of your vehicle. Looking through your rear-view and side-view mirrors alone will not be enough to position your car correctly. Drivers must look over their left and right shoulders through the side windows to position their vehicle in relation to the curb line when parallel parking.

The image shows the curb line when the vehicle’s rear-end is positioned beside the curb, and the driver is looking over their left shoulder. In this situation, the door handle makes an appropriate reference point.

This image demonstrates what the curb line would look like through the side window, when the vehicle’s rear end is aligned with the curb and the driver is looking over their right shoulder.
