Tesla Speeding Alert: Know When a Monitored Drive Goes Too Fast

A Tesla speeding alert tells you when your car is driven too fast without your owner phone detected. Sentry Driver connects to your Tesla through the official Fleet API and uses Bluetooth owner-detection to check whether you’re present — so when a monitored drive crosses a speed you’ve set, a push notification can land on your phone shortly after the car reports it. There’s no dongle to plug in, and nothing for the other driver to install or carry.

How a Tesla speeding alert works

Sentry Driver is an owner-only app. You install it; the people who borrow or share your Tesla install nothing and do nothing. Here’s the flow:

• Official connection - It links to your Tesla over Tesla’s official Fleet API using OAuth. Your Tesla login is never stored.
• Automatic owner-detection - Bluetooth senses whether your owner phone is near the car. When your phone is present, owner-absence alerts stay quiet. When it is not present, monitoring switches on by itself — no key handoff, no toggling.
• Near real-time speed - During a monitored drive, Sentry Driver reads your Tesla’s speed from the Fleet API. Cross your threshold and the alert reaches your phone as telemetry and push delivery allow.

Because the detection is automatic, you don’t have to remember to “arm” anything before you hand over the keys. If your owner phone is not detected, it’s watching.

What triggers a speeding alert

You decide what “too fast” means. Set a speed threshold that fits the driver and the roads they’re on, and Sentry Driver alerts you only when that line is crossed — not for every drive.

Speeding is just one of the behaviors it watches for. Depending on how you set it up, you can also get alerts for hard braking, late-night driving, leaving or entering specific zones, and accidents — plus a weekly driving summary so you can see patterns over time. For a parent handing the keys to a new driver, that turns a guessing game into a real conversation. See how families use it on our teen drivers page.

Tesla’s built-in speed limit vs. a real-time alert

Tesla does offer a native tool here, and it’s worth understanding the difference. Tesla’s Parental Controls can enforce a speed cap — “Limit Speed,” set from 50 mph up where supported. But it’s a PIN-protected restricted mode that applies to the whole vehicle, not to Sentry Driver’s owner-phone detection, so you have to switch it on and off by hand every time the driver changes. Outside that restricted mode, Tesla’s native tools are not built around owner-absence speeding push alerts.

Sentry Driver takes the opposite approach. It doesn’t cap, slow, or control your Tesla — it gives you visibility. You can separate owner-present drives from monitored drives, get a timely alert when a threshold is crossed, and scroll back through trip history afterward. The two can even work side by side.

Setting up your first Tesla speeding alert

Getting started takes a few minutes:

1. Download Sentry Driver and sign in.
2. Connect your Tesla through Tesla’s official OAuth login.
3. Set your speed threshold (and any other alerts you want).
4. You’re done - Bluetooth owner-detection handles the rest, alerting you when your owner phone is not detected.

It works with supported Model 3, Y, S, X, and Cybertruck vehicles that meet Tesla Fleet API and telemetry requirements, with multi-car support if you have more than one in the garage.

Sentry Driver is available now on Google Play for Android and on the App Store for iOS, with a free 7-day trial. Check our pricing plans to find the right fit — and get a timely alert the next time a monitored drive goes too fast.
