A truck driver plans a delivery using a car navigation app through a low underpass, a residential no-truck zone, and a steep descent. What is the best professional approach?

1. Use truck-appropriate route planning, verify restrictions, dimensions, mass, and descent control before departure
2. Trust the car app because it gives the shortest time
3. Drive through slowly and decide at each obstacle
4. Ask another driver to lend a tachograph card for the difficult section
