1. A camera monitor system for a vehicle comprising:
at least one forward facing camera having a field of view at least partially encompassing a route of forward travel of the vehicle;
a camera monitor system (CMS) configured to receive a video feed from the at least one forward facing camera;
the CMS including a processor and a memory, the memory storing instructions for causing the processor to identify a clearance object in the video feed, for causing the processor to determine a clearance height of the clearance object from the video feed, and compare the clearance height of the clearance object to a height of a trailer, and initiate a response in response to the clearance height of the object being less than or equal to the clearance height of the trailer; and
wherein determining the clearance height of the clearance object comprises at least identifying a visual clearance indicator within the video feed using image analysis, and interpreting the visual clearance indicator, wherein determining the clearance height of the clearance object comprises determining a first clearance height by identifying the visual clearance indicator within the video feed and interpreting the visual clearance indicator and identifying a second clearance height by determining a pixel length from an edge of the clearance object to a road surface and converting the pixel length to a real world distance, and selecting one of the first clearance height and the second clearance height as the clearance height.
