Duel (1971) Timeline Explained – Every Event in Order

The movie never reveals the truck driver's motivation or identity. From the first encounter, the driver appears deliberately hostile, speeding up when David tries to pass, using the air horn to intimidate, and then actively trying to kill him. This ambiguity is intentional; the truck becomes an unstoppable force of nature rather than a character with comprehensible motives. The driver is shown only through hairy arms and worn jeans, keeping the threat anonymous and heightening the psychological terror.

Foreshadowing: The gas station scene establishes early that the driver is watching David even when out of sight, suggesting premeditated malice rather than random road rage.

The truck driver's identity is never revealed. The film deliberately keeps the driver hidden, visible only as a pair of hairy arms and worn jeans when watching David at the gas station. This anonymity is a key element of the film's tension, making the threat feel faceless and unstoppable rather than a specific person David could reason with or confront directly.

The gas station attendant earlier points out that David's radiator hose is worn and needs replacement, but David dismisses it as something that can wait. This detail pays off during the high-speed chase when the hose finally gives out, disabling his car and forcing him toward the cliff edge. It's a consequence of his earlier negligence that directly threatens his life.

Foreshadowing: The gas station attendant explicitly warns about the radiator hose shortly after the first encounter, establishing the mechanical vulnerability before it becomes critical.

David wedges his briefcase on the accelerator to maintain speed while he prepares to jump clear of the car. As the truck bears down on him, he leaps out at the last moment, rolling away to safety while the truck, unable to stop in time, plummets off the cliff and crashes below. The briefcase acts as a makeshift cruise control, allowing him to abandon the vehicle without slowing down.

David's frustration and pride drive him to keep trying. Each time he attempts to overtake, the truck accelerates to block him, creating a cycle of escalation. His argument with his wife earlier reveals he has a pattern of avoiding confrontation, but on the road, he refuses to back down. The truck's deliberate taunting, slowing down when David falls back, then speeding up when he tries to pass, makes it impossible for him to simply accept being blocked.

Foreshadowing: The phone call with his wife reveals his reluctance to confront problems directly, making his insistence on battling the truck even more telling about his psychology.

David enters a diner believing the truck driver is inside among the patrons. He confronts a suspicious-looking man, gets into a fight, and watches in confusion as the man drives away in a completely different truck. Meanwhile, the menacing tanker remains parked outside, unchanged. This scene deepens the mystery, either David confronted the wrong person, or the real driver was watching from inside without engaging.

After surviving the cliff confrontation, David stands atop the cliff throwing stones into the abyss as the sun sets. This primal act represents his release of pent-up adrenaline and a return to a more primitive, emotional state. Having been stripped of his civilized identity as a businessman in his nice car, he now expresses survival through raw, instinctual behavior, a cathartic release after the harrowing ordeal.

When David tries to use a phone booth to call for help, the truck deliberately targets him while he's trapped inside. This demonstrates the driver's absolute determination to kill David, no matter where he seeks help or refuge, the truck will find him. The truck essentially cuts off David's only avenue of escape from the road, forcing him to face the threat alone.

During the gas station phone call, David's wife presses him to stand up to a difficult client rather than avoiding confrontation. David admits he's avoiding the issue and admits this is a pattern for him. This conversation establishes his psychological vulnerability and fear of direct conflict, ironic given the escalating confrontation on the road that he cannot avoid.

David encounters a stalled school bus blocking part of the road, creating a dangerous situation where he must navigate around it while the truck continues its pursuit. This adds another layer of peril, forcing David to maneuver through a narrow space with an oncoming vehicle in the other lane, nearly causing a collision that would have been fatal.

After the phone booth attack, David attempts to hide, hoping the truck will pass. However, the truck stalks him and refuses to leave, forcing him to confront that there is no safe place. This moment breaks David's hope of waiting out the situation and pushes him toward the final confrontation, he realizes he must face the truck directly to survive.
