How can the consumption of cannabis products affect the driver?

You answered correctly. The consumption of cannabis can negatively affect driving in several important ways. It reduces awareness of the surrounding traffic, making it harder to notice other road users or react to their actions. It also decreases the ability to concentrate, so it becomes more difficult to pay continuous attention to the driving task and make safe decisions. These effects increase the risk of accidents and are why driving under the influence of cannabis is prohibited. Reduced sensitivity to glare, as mentioned in answer 3, is not a typical effect of cannabis—that is more associated with alcohol. For the theory test and safe driving, remember that cannabis affects concentration and awareness, both critical for safe participation in road traffic.
