Devices and methods for aiding drivers in properly positioning a motor vehicle within the lane of a roadway. Devices include visible indicia displayed on the vehicle windshield. The indicia can be positioned such that when the vehicle is properly positioned with respect to the left and/or right side lane marker, the visible indicia will be in the driver's line of sight in a position near the lane marker. If the driver steers the vehicle over the lane marker, the indicia should appear to be over the lane marker as well, in many embodiments. Some indicia include one or more line shaped portions which appear to converge and appear parallel to the lane marker. Other indicia may include one or more dots, which can be oriented in a line to appear parallel with the lane marker, and/or appear at different left to right positions with respect to the lane marker. Some indicia are light emitting devices, which can include fiber optic devices and/or LEDs.
