A vehicle parking guide includes an elongated body having a triangular cross-sectional shape. Included on one of the sides of the triangular body is an adhesive section. The adhesive section allows the triangular body to be selectively attached to a floor surface, such as that of a garage, to mark a desired parking location. The vehicle parking guide is positioned so that one of the tires of a vehicle must pass up and over the apex of the guide. The physical sensation of rolling up and over the triangular shape of the parking guide serves as feedback to the vehicle's driver to stop the vehicle after the parking guide is passed over, thereby parking the vehicle precisely at the predetermined parking location.

A modular highway warning strip system comprises a first plurality of segments assembled together to form a first warning strip subassembly and a second plurality of segments assembled together to form a second warning strip subassembly. Connecting segments join the two subassemblies together using magnetic connectors.
