Is a truck driver entitled to assume that other drivers would be paying attention to their signal lights?

36. I turn then to the respondent’s actions. I accept that in the circumstances, the respondent was properly positioned in the left lane to execute the required wide right turn. The applicant says the respondent should have checked their blind spot before turning. However, I find the respondent was reasonably focussed on the tight turn they had to negotiate and the construction crew in the intersection. I also find the respondent was entitled to assume that other drivers would be paying attention to their truck’s signal lights and would proceed with the necessary degree of caution the circumstances required. See Stewart v. Dueck, 2012 BCSC 1729 at paragraph 54.
