Your Company Tesla, Driven by Someone Else? Know How It Went

The Car Is Assigned to You - So Is the Responsibility

A company car is usually yours in every practical sense: you drive it daily, you answer for tickets, damage, and mileage, and now and then you hand the keys to someone else - your partner for a school run, a colleague for an errand, a valet at a client dinner. Tesla company car monitoring with Sentry Driver is about knowing how the car was driven in those moments when it wasn’t you behind the wheel.

Sentry Driver is an owner-only app. You connect the Tesla assigned to you (with the permission of whoever owns it, if that’s not you), and monitoring activates automatically when your phone is not present. Nobody else installs anything.

Real-Time Alerts for the Drives You Don’t Take

When someone else has your company car, the things worth knowing are speed, harsh handling, and incidents. Sentry Driver surfaces all three as they happen:

• Speeding alerts when the car passes the threshold you set, with speed, time, and location
• Hard-braking and rapid-acceleration events, logged per drive
• Accident detection with a timely alert and location so you can respond fast
• Geofence zones for places the car should stay in, or shouldn’t go
• Curfew alerts if you want to know about late-night use

Tesla’s native tools are not built around owner-absence speeding or hard-braking push alerts. Getting that visibility from the car itself is the gap Sentry Driver fills.

More Than One Car on Your Account?

Subscription tiers cover 1, 2, 3, or 5 Teslas on a single account, each with its own rules:

• Per-vehicle alerts so you know which car triggered which event
• Trip history for each car: distance, duration, max speed, and behavior counts
• An event log with timestamps and locations for anything that crossed a rule

If you own several Teslas - a family with more than one, or cars you lend or rent out - the multiple Teslas page covers that setup.

Records for When You Have to Explain

When something goes wrong with a car you’re responsible for, data helps. Sentry Driver gives you timestamped records you can lean on:

• Accident claims: show recorded speed, location, and hard-braking context around the time in question
• Damage disputes: know when the car was driven, where it went, and how hard it was pushed
• Mileage and usage: confirm how the car was used while it was out of your hands
• Insurance: provide trip records when they’re requested

Visibility, Not Surveillance

Sentry Driver reports how the car was driven - speed, braking, incidents, trips - and nothing about the person. It doesn’t identify who is driving and doesn’t touch their phone. It’s owner-only and runs on OAuth: your Tesla password is never seen or stored by us; we hold only the access token Tesla issues.

Let anyone who drives your car know it’s monitored. Our terms require it, and drivers who know tend to drive more carefully anyway. Sentry Driver is sold to individuals for their own vehicles; if the car belongs to your employer, connect it only with their authorisation.

Frequently Asked Questions

Does the other driver have to install anything?

No. Whoever drives the car installs no app, pairs no phone, and carries no device. Monitoring runs through Tesla’s Fleet API on your account.

The car is leased or owned by my employer. Can I connect it?

You can connect a Tesla you own or are authorised to connect. If the car belongs to your employer or a leasing company, get their OK first. Sentry Driver is an app for individuals; it isn’t a fleet-management tool for monitoring staff.

Does this need a dongle or OBD device?

No. There’s no hardware to plug in. Sentry Driver works with Model 3, Y, S, X, and Cybertruck directly through Tesla’s official Fleet API.

Can the alerts help with an insurance or accident claim?

Yes. Monitored drives record max speed, and the event log captures speed, time, and location for violations - data that can support or refute a claim about how the car was being driven.

Is this monitoring the driver or the car?

The car. Sentry Driver reports how the vehicle was driven. It doesn’t identify who was driving and doesn’t track anyone’s personal phone or anything outside the vehicle’s own telemetry.
