For thousands of commuters in Lima, the daily rush hour is already a test of patience. The gridlock on avenues like Angamos or the congested stretches of the Rímac district are defined by a stressful symphony of honking horns and bumper-to-bumper traffic. But recently, a new predator has emerged in these traffic jams: the “Montachoques.”
This calculated fraud doesn’t rely on high-speed collisions or dramatic accidents. Instead, it is a game of inches and psychological pressure. The scam is simple but effective: a driver, sensing a vulnerable target in a slow-moving line of cars, intentionally reverses their vehicle into the car behind them. Once the impact occurs, the fraudster immediately pivots the narrative, stepping out of the car to aggressively accuse the victim of rear-ending them.
The goal is rarely a legal battle; it is a quick payout. By leveraging the chaos of Lima’s traffic and the victim’s desire to avoid a lengthy police report or insurance claim, these scammers pressure drivers into paying cash on the spot to “settle” the matter and clear the road. Police sources indicate that the fraud is particularly prevalent in areas with low transit officer visibility, such as Prolongación Tacna in Rímac, Parinacochas in La Victoria, and various points across Surco and Miraflores.
Despite the rise in reported cases on social media platforms like TikTok and Instagram, formal police reports remain surprisingly low. According to the National Police of Peru (PNP), many victims choose to walk away once a police officer arrives at the scene, opting to absorb the stress or the minor financial loss rather than endure the bureaucracy of a formal complaint.
The Anatomy of a Setup
The “Montachoques” strategy relies on the common driving habit of “tailgating”—where drivers leave dangerously small gaps between vehicles. This proximity makes it nearly impossible for a driver to prove they weren’t moving when the impact occurred, unless they have digital evidence.
Recent footage from dashcams has exposed the precision of these attacks. In one instance recorded in Chorrillos along the Costa Verde, video shows a line of stopped cars. The vehicle in front begins a slow, deliberate reverse maneuver until it hits the car behind. The driver then immediately exits the vehicle, shouting accusations and claiming the victim had surged forward. The scam collapsed only when the victim informed the aggressor that the entire event was captured on camera; the fraudster vanished from the scene almost instantly.
In other cases, the intimidation is amplified. Police sources report that some scammers operate in pairs. When the collision occurs, two people exit the “affected” vehicle to “atarantar”—or overwhelm—the victim. By creating a scene and using aggressive language, they aim to disorient the driver, making a quick cash payment seem like the only way to restore peace and resume their journey.
The Legal Risks for Fraudsters
While the scammers view these incidents as “easy money,” the legal reality is far more severe. According to Aaron Alemán, founding partner of the firm Alemán y López, these actions can trigger multiple criminal charges depending on the evidence available.
When a driver intentionally causes a collision, they are not just committing a traffic violation; they are committing a crime against property. If a video recording proves the act was deliberate, the perpetrator can be charged under the Peruvian Penal Code. The legal implications are broken down as follows:
| Legal Classification | Penal Code Article | Potential Penalty |
|---|---|---|
| Daño Simple (Simple Damage) | Article 205 | Up to 3 years imprisonment and 60 day-fines |
| Coacción (Coercion) | Article 151 | Up to 2 years imprisonment |
| Denuncia Calumniosa (False Accusation) | Article 402 | Up to 3 years imprisonment and 365 day-fines |
The charge of coacción applies if the scammer uses threats or violence to force the victim to pay. If the fraudster attempts to formalize a false police report to extort the victim, they risk a charge of denuncia calumniosa for misleading the judicial system.
How to Protect Yourself and Your Wallet
Preventing these scams requires a combination of defensive driving and a strict adherence to legal protocols. Colonel (r) Franklin Barreto, former head of the Traffic Accident Investigation Division of the PNP, emphasizes that the best defense is distance. He recommends maintaining a gap of 2 to 3 meters between vehicles, even in heavy traffic.
“This distance allows the driver to react,” Barreto explains. “If the vehicle in front begins to reverse, you have the space to honk the horn or use a phone to film the incident, which provides the necessary evidence to debunk the fraudster’s claim.”
If you find yourself in a suspicious collision, the Peruvian Association of Insurance Companies (Apeseg) suggests the following steps:

- Contact your insurer immediately: Request an insurance procurator to attend the scene. Their professional assessment can officially document that you were not the responsible party.
- Move the vehicles: Contrary to popular belief, if We find only material damages, the National Transit Regulations require vehicles to move to the right to avoid obstructing traffic.
- Demand a formal process: Refuse “quick arrangements” with strangers. Insist on going to the police station for a formal peritaje (technical inspection) and a dosaje etílico (blood alcohol test).
- Gather evidence: Check for dashcam footage, security cameras from nearby businesses, or contact information from witnesses who saw the front car reverse.

As the “Montachoques” modality continues to spread via social media warnings, the PNP is encouraged to increase patrols in identified hotspots. The next critical step for victims will be the formalization of more complaints to allow prosecutors to identify repeat offenders and move these cases from simple traffic disputes to criminal fraud investigations.
