Ulysses S. Grant was arrested for speeding in his horse-drawn carriage. There were three reported arrests, all related to speeding horses in Washington, D.C. The most famous incident happened in 1872 while Grant was president. Police officer William Henry West stopped Grant for racing his horse and buggy at high speed, warned him, and then arrested him the next day for speeding again. Grant paid a $20 bond but did not appear in court, forfeiting the bond. This arrest made Grant the only U.S. president known to have been arrested while in office. The event was later confirmed by police accounts and has been described as a symbol of the rule of law, with Grant showing respect for the officer's duty.
