Because matatus have different rules, all the other traffic rules apply except:-
If a matatu tries to overtake you accerelate coz if you let them they are going to stop in front of you after overtaking.
If matatu displays hazard it means they are picking wathii ovyo ovyo and you can overtake at your pleasure.
If a matatu is behind/front of you and a cop waves stop it means he/she stopping the matatu not you.
If a matatu begs for way dont yield but give way for others.
............Always remember,be rough to matatus and kind to others.
