Hours-of-service rules limit how long a commercial driver may drive and be on duty. The US and Canada have different rule sets, and both have exceptions that only a trained safety professional should apply.
For a dispatcher, the practical lesson is simple: plan loads that fit the hours the driver actually has, read the ELD before planning, and never ask a driver to "make it work".
Explore both rule sets with fictional logs in the HOS Simulator. The academy's HOS rule set is reviewed periodically — check the "last reviewed" date on the Regulatory Updates Center.
