Explanation

Uncontrolled intersection: the rule

The rule

At an uncontrolled intersection, a driver yields to any vehicle approaching from the right.

The reasoning

Residential grids are full of these. With nothing posted, the same right hand convention applies, so the driver with a vehicle on their right yields. If a vehicle is clearly in the intersection first, it keeps its priority.

The usual mistake

Drivers treat the wider or busier looking road as the main road. Width does not create priority. Unless a sign or a marking says otherwise, the right hand rule decides it.
