Final answer:
In work zones, motorists should be alert, comply with posted signs, maintain a cautious speed, and be prepared to make safe stops without abruptly slowing down.
Step-by-step explanation:
When driving in work zones, you should stay alert, obey the signs that are posted, and do not slow speed abruptly, but be prepared to stop. It is not advised to activate your four way flashers before entering the work zone unless the situation specifically requires it, and you should certainly not increase speed so as not to impede traffic. Instead, maintain a cautious speed, watch for workers and equipment, and be ready for sudden stops or shifts in traffic patterns.
