Some people argue that lane splitting helps motorcyclists speed up the flow of traffic because there are fewer vehicles occupying a single lane. Supporters also argue that lane splitting does not increase the risk of injury to motorcyclists, that it may help remove the motorcycle from a dangerous situation, and that Maryland lane-splitting motorcycle accidents are less severe for motorcyclists than rear-end accidents. However, even where it is legal, lane splitting can be dangerous and motorcyclists have to exercise caution to do it safely.
