Find the present location on the map. This can be done by unfolding the map and locating key points near a location such as major intersections, landmarks or cities. Be sure to check the map's legend, usually located in a bottom corner, if any symbols seem unfamiliar or difficult to interpret.
Locate a specific destination location using the same method.
Using an object such as a pencil or finger, trace a route between the starting point and the destination point using the roads labeled on the map. Usually, this should be the quickest and most direct route. However, feel free to plan a trip along roads that pass major landmarks or points of interest if desired. These points will often be labeled by a specific symbol which is located in the map's legend. For instance, an airport will usually be denoted by an airplane, while a campground may be marked by a triangle representing a tent.
Take note of the planned route and roads being used. Interstate highways will usually be recognizable as thick lines either blue or green in color marked by a blue "shield" symbol with a red top that contains the highway number. U.S. highways, meanwhile, should be marked by a thick red line and labeled with a white or off-white shield symbol. Smaller highways are labeled by using thinner lines and are marked with the highway number, while simple roads will usually be displayed using a black solid line with the street name written above it.
Look for an inset that shows greater detail around the starting or destination city. While some maps may not have this feature, many include a blown up map of larger metropolitan area's with more detailed street and highway views. This can be helpful when navigating city streets where precision and detail is key to ensuring a timely arrival. These insets vary in location according to the specific map.
Measure the direction and distance traveled, if necessary. Most maps include a scale and a compass rose near the legend. The scale allows users to measure the distance between two points in miles according to their distance apart on the map. For example, on a particular map, 1 inch may translate into 20 miles. The compass rose, meanwhile, shows users the cardinal directions and the map's orientation. For ease of use, most maps are displayed so that North is facing up.
Take note of major landmarks or intersections along the planned route. Use these a waypoints during the trip to ensure the route is going as planned.
Fold the map so that the planned route can be easily read while driving, if possible. This will make it easier to reference the map in times of need while on the road without having to unfold it and relocate everything. If needed, jot down the directions on a sheet of paper for easier access.
Be prepared for detours. Occasionally, a road or highway may be closed due to extenuating circumstances or could require a toll to pass. In some cases, these hazards may be marked on the map using symbols within the map's legend. If they aren't, be prepared to pull over and plot an alternate route to avoid any obstacles.
