Highway routing
For delivery planning, at 7h 42m one-way, same-day delivery is achievable but the round trip exceeds a single driver shift, so plan an early dispatch or a driver relay. These are estimates — real ETAs shift with traffic, checkpoints, and multi-stop detours. Live GPS tracking & route monitoring shows actual vehicle progress and customer-facing ETAs instead of a fixed guess.
