On 21 December 2024, a multiple-vehicle collision involving a passenger bus, a car and a B-double road train occurred in Lajinha, a district of Teófilo Otoni, Minas Gerais, Brazil, on the BR-116 highway.

With an extensive road network and a busy flow of heavy trucks, especially in granite-producing regions in northern Minas Gerais, serious crashes are frequent, including during the intense end-of-year season.

[7] According to data from the National Transport Confederation [pt] (CNT), the state of Minas Gerais has the most crashes and fatal victims on Brazilian highways.

[8] The National Department of Transport Infrastructure [pt] (DNIT) said that the speed limit radar near the crash site was removed after the end of the contract with the company responsible for the equipment.

[11] Initial reporting by firefighters claimed that a passenger bus travelling on the BR-116 highway from São Paulo to Bahia[a] had a tire blowout, causing it to lose control and collide with an oncoming B-double truck at around 4 a.m. local time.

[12][13] However, according to the Federal Highway Police, the collision likely occurred when a granite block fell from the truck and hit the bus, which consequently lost control and caught fire.
