The candidate reports a design question about detecting a prolonged stopped cab in a safety-sensitive journey and triggering an alert. Employer confirmation is absent. The source's scenario details are incomplete for implementation.

Original answer outline: Ask for the actual condition, sensor evidence, false-positive cost, escalation owner and delivery guarantee. Define explicit states and stable alert identity. Our lesson adds late-telemetry handling as an original extension; the report does not verify that extension was asked.
