Our primary concern from Transport Canada is ensuring the safety of our roads. One of the key ways we do that is to mitigate the risk of accidents related to fatigue. That is the entire purpose of the hours of service regulations. A very large exemption of this nature would allow for a significant increase in the risk of fatigue. If drivers are able to consistently exceed what we think are regular limits and not get the rest that they need, then they would be able to get overfatigued.
