A method for assisting a driver includes determining that a host vehicle and first and second surrounding vehicles are approaching an intersection on at least two different road segments; determining when the first and second vehicles have stopped at the intersection; determining when the first and second vehicles proceed through the intersection; and identifying an actual order-of-progression of the first and second vehicles through the intersection. Simultaneously or sequentially with determination of the actual order-of-progression, attempting to determine a present geographic location of the host vehicle and consulting an on-board database to attempt to identify a regulatory order-of-progression for the present geographic location. If the regulatory order-or-progression is identified, the driver is advised regarding the regulatory order-of-progression. If the attempt to identify the regulatory order-or-progression is not successful, the driver is advised regarding the actual order-of-progression.
