Identify what the current mode asks
Real Monster Truck Games 3D describes missions, stunt racing, and a free mode. A mission finish and open exploration are different goals. Read the selected mode's visible objective before judging a drive by its duration or distance. If a mission asks you to reach a finish, the relevant question is how the route leads there. If you are exploring freely, an unmarked detour may be the point of the session.
Connect each arrow to the road ahead
The source explicitly mentions following direction arrows. Use an arrow to locate the next part of the route, then inspect the ground between your truck and that destination. An indicated direction does not itself tell you the surface is flat or the next turn can be taken at your current pace. Reading marker and terrain together is especially useful when a large vehicle obscures part of the near road.
Evaluate a mission failure concretely
The listing says a failed stunt racing level starts again. Before repeating it, identify the route decision that caused trouble: losing the indicated path, approaching a turn poorly, or misunderstanding the finish direction. Those are more actionable observations than calling the whole course impossible. Keyboard controls are listed generically, so confirm the game's actual bindings rather than importing keys from another truck game. Use the marker to orient yourself, then drive the visible terrain.
Racing
Monster truck missions and open driving offer different reasons to follow a marker and different ways to judge a useful run.
