Burning tires, as well as vehicles such as trucks, cars and vans were blocking several points in the central-western agricultural state of Mato Grosso, which largely supports Bolsonaro, reported the company which manages the highway in the state.

It was not immediately clear if the protests were being organized by a particular group. Brazil has a powerful, loosely organized truckers' movement that is heavily pro-Bolsonaro.

Local media reported road blockages in at least five other states, including Rio de Janeiro and Sao Paulo.
