Without line markings, we would have chaos on our roads. For some business, without proper, well organised marked lines in their car parking areas, they could also be losing their customers.
Once you step out of your own house and start driving your vehicle, you see different line markings along your way. But what if there are no line markings? What do you think will happen?
Every driver would cruise around the roads as they please, accelerate and take random stops and turns. Pedestrians would walk, run and cross our roads everywhere and anywhere and people with disabilities would most likely find traffic impossible to navigate.
