FAQ
What are the hidden costs and complexities of sensor integration that are often overlooked?
The hidden costs include ongoing data plans for cellular connectivity and IT labor for maintaining API connections and troubleshooting data flow issues. Integration typically requires significant configuration, middlewar...

What's the one clause that must be in my driver agreement regarding remote immobilizers?
Beyond just getting consent, you need their explicit acknowledgment that the vehicle is company property, subject to remote disabling for policy violations or unauthorized use, and that the driver shouldn't assume any ex...

Do I need to notify a driver before immobilizing the vehicle?
From a pure risk management standpoint, absolutely. A sudden loss of power, even at a low speed, can cause panic and lead to an accident. The best practice is to contact the driver first, with the only real exception bei...

Are there states where remote immobilizers are explicitly illegal?
The laws are still changing. Some states have consumer protection laws about disabling devices on financed vehicles that could be interpreted broadly. For commercial fleets specifically, it's much less clear, which is th...

Can I legally disable a company vehicle if an employee is late on payments for a personal use program?
That's a high-risk area. If the vehicle is seen as being in the employee's possession under a lease agreement, hitting the kill switch could be viewed as a 'self-help repossession,' which is actually illegal in many stat...

What is considered a high idle time percentage for a cement mixer?
If a mixer is idling 30% of its engine-on hours, that's a major red flag. Well-managed fleets aim for under 20%, but it rarely dips below 15% due to unavoidable operational pauses built into concrete placement.

Should idle time data be linked to driver bonuses?
Be very cautious with that approach. It often incentivizes wrong behaviors like poor washouts or shutting off during necessary brief waits. The data is better used for coaching and process review, such as analyzing why s...

Can idle time analytics be manipulated by drivers?
Yes, drivers can slightly increase drum rotation speed to drop below the idle threshold, which ironically often uses more fuel than efficient low-speed idling. This makes the data look better while actual waste increases...

Does weather significantly impact idle fuel waste in cement mixers?
Absolutely. In cold climates, necessary warm-up idling to protect the engine and hydraulic systems can easily double standard idle fuel use. This is a seasonal cost that should be factored in, not treated as an efficienc...

Does the AIS 140 emergency button need its own power source?
No, the button is typically powered by the VTU. However, the circuit must include protection against short circuits and voltage spikes from the vehicle's electrical system, which is a common point of failure in implement...

What happens if GPS signal is lost when the emergency button is pressed?
The VTU must still send the emergency alert using the last valid cached location. The alert includes a status flag indicating the GPS fix was lost. Early designs often failed to properly handle this scenario.

What are the exact signal requirements from the emergency button to the VTU?
The emergency button needs a clean, debounced digital input to a dedicated GPIO pin—usually a ground pulse. The VTU firmware must be explicitly configured to recognize this as the emergency trigger. Proper debouncing is...
