Global Positioning System navigation devices, better known as GPS, may be one of the most useful tools drivers have. But they are not perfect, and relying on them too heavily can put you in risky situations.

Consider a few real-world examples:

• A driver near Santa Fe, New Mexico, followed his GPS to avoid traffic, only to end up at a dead-end facing a 200-foot cliff.

• A 70-year-old driver in Texas said his GPS once directed him into oncoming traffic. He now jokingly calls it “Christine.”

• A Pennsylvania driver adjusting a new GPS on a dark road rear-ended a stopped vehicle just over a hill.

With millions of vehicles equipped with GPS, these systems can absolutely improve safety. They help drivers anticipate turns, reduce last-minute maneuvers, and lower stress in unfamiliar areas.

But like any tool, they need to be used wisely.

Keep Your Focus on the Road

GPS directions are not always accurate. Maps can be outdated, and systems can glitch. Use your judgment and don’t blindly follow directions that don’t make sense. Most importantly, don’t stare at the screen while driving.

Set Your Route Before You Go

Adjusting your GPS while driving is a major distraction. Enter your destination and review your route before you start moving. If you need to make changes, pull over safely first.

Don’t Block Your View

If you use a portable GPS, make sure it doesn’t obstruct your line of sight. Some states even restrict windshield mounting, so it’s worth knowing the rules where you drive.

Preview Your Route

If you’re heading somewhere new, take a minute to review the route ahead of time. Many systems allow you to preview turns or simulate the trip. A quick look can help prevent surprises later.

Keep It Out of Sight When Parked

Portable GPS units can attract thieves. When you leave your vehicle:

• Store the device out of sight

• Remove charging cables

• Wipe away suction cup marks from the windshield

A GPS can make driving easier, but it shouldn’t replace awareness and good judgment. Think of it as a guide, not a decision-maker.
