Why Google Maps May Pick a Slower Route & How to Change It

Google Maps can recommend a slower route when its algorithms prioritize factors like traffic predictions, road closures, or fuel efficiency over raw speed. You can change this by adjusting your navigation settings, choosing a different route manually, or using alternatives like Waze for more aggressive time-saving. Here’s a detailed look at why this happens and what you can do about it.

How Google Maps Chooses Routes

Google Maps uses a complex algorithm that considers multiple data sources to determine the “best” route. The primary inputs include:

• Real-time traffic data from anonymous GPS signals of other users.
• Historical traffic patterns for that time of day and day of week.
• Road closures and construction reported by users or local authorities.
• Speed limits and typical speeds on each road segment.
• Distance and the number of turns or intersections.

Google’s default is to minimize travel time, but it also factors in reliability—a route that is 2 minutes faster but has a 30% chance of a 15-minute delay might be ranked lower than a slightly slower but more consistent route. This is why you might see a recommendation that isn’t the absolute fastest in ideal conditions.

Why It Might Pick a Slower Route

Several specific reasons can lead to a slower route being recommended:

• Traffic prediction: The algorithm may know that the faster road will be congested by the time you reach it, so it routes you around it.
• Road closures: A road on the direct path may be closed, forcing a detour that adds distance but avoids a dead end.
• Safety or road quality: In some regions, Google Maps may avoid unpaved roads, steep grades, or highways if it detects a preference for safer or more scenic routes (this can be changed in settings).
• Fuel efficiency: On some routes, Google may prioritize fuel economy over time, especially if you’ve enabled eco-friendly routing.
• User reports: If many users have reported delays or hazards on a specific road, it will be deprioritized.

Additionally, if you have set a preference to avoid highways, tolls, or ferries, the app will deliberately choose a longer route that complies with those restrictions.

How to Change the Route in the App

If you see a route that seems slower, you can manually override it:

1. Enter your destination and let Google Maps calculate the initial route.
2. Swipe up on the bottom panel to see the list of alternative routes (if available).
3. Tap on a different route to select it—the time and distance will update.
4. If you want to avoid a specific road, tap the route, then tap the three dots menu, and select “Route options” to toggle off highways, tolls, or ferries.
5. You can also drag the route line to a different road to force a custom path.

For a more permanent change, go to Settings > Navigation Settings. Here you can turn off “Prefer fuel-efficient routes” or adjust your vehicle type (car, motorcycle, etc.) which changes route preferences.

Using Route Options and Avoidances

Under Navigation Settings, you’ll find several toggles that directly influence route selection:

• Avoid highways – adds time but avoids interstates.
• Avoid tolls – may take longer but saves money.
• Avoid ferries – useful if you’re in a hurry or dislike water crossings.
• Prefer fuel-efficient routes – this can add minutes but saves gas.

If you’re late for an appointment, turn off the fuel-efficient option and uncheck any avoidances that aren’t critical. Google will then prioritize the fastest route based on current traffic.

Common Problems and Misconceptions

A frequent complaint is that Google Maps sends you on a “scenic” route that seems illogical. This often happens because the app is using real-time data that you can’t see—for example, a crash on the main road that hasn’t been reported yet but is causing a slowdown. Another misconception is that Google always knows best; in reality, it’s a prediction, not a guarantee. Also, if you have poor GPS signal or an outdated app version, route calculations can be off.

Another issue is that Google Maps sometimes suggests a route with many turns that feels slower, but in practice, it avoids traffic lights or congested intersections. If you’re in an unfamiliar area, it’s usually safest to follow the recommended route unless you have strong local knowledge.

Comparing Google Maps to Other Apps

If you’re frustrated with Google’s choices, consider alternatives:

• Waze – Owned by Google but uses a more aggressive, community-driven approach to find the absolute fastest route, often at the expense of residential shortcuts.
• Apple Maps – Has improved significantly and sometimes offers simpler routes with fewer turns.
• Here WeGo – Good for offline navigation and often suggests routes that are more direct.

Each app has its own algorithm; you might find that one consistently matches your driving style better. It’s worth trying a different app for a week to see if it reduces your commute time.

When to Trust the Slower Route

There are times when the slower route is actually the better choice. If Google predicts that a faster road will be jammed by the time you arrive, it’s often right. For example, if you’re driving during rush hour, a slightly longer route on side streets can save you 10 minutes of stop-and-go traffic. Similarly, if you’re low on fuel, the eco-friendly route might be worth the extra time. Trust the algorithm when it has a clear reason (like a red traffic line on the map) and you’re not in a life-or-death hurry.

Frequently Asked Questions

Why does Google Maps sometimes take me on a longer route?

Google Maps may choose a longer route to avoid traffic, road closures, or to comply with your avoidance preferences (tolls, highways). It also considers historical data and may predict congestion on the direct route by the time you reach it.

How do I force Google Maps to take the fastest route?

Open the app, go to Settings > Navigation Settings, and turn off “Prefer fuel-efficient routes.” Also, uncheck any avoidances like highways or tolls unless you really need them. Then, when you search for a destination, tap the route you want from the list instead of just starting navigation.

Can I make Google Maps avoid a specific road?

Yes, after entering your destination, tap the route, then drag the blue line to a different road. You can also add a stop that forces a detour, but the drag method is cleaner for avoiding a single road.

Why does Google Maps show a route that’s slower than the one I know?

The app may have real-time data about a crash or delay on your preferred road that you don’t know about. It also uses historical patterns that might be more accurate than your personal experience, especially at different times of day.

Is Waze faster than Google Maps?

Waze is often faster because it aggressively reroutes around traffic using real-time user reports. However, it may send you through residential areas that feel slower. Google Maps is more conservative and tends to favor major roads, which can be more reliable.
