You can open them from internal and external sides. Also, they are on one side of the vehicle. 

A few have them on the front side and prevent sudden injuries. The concept was to reduce injuries and sudden accidents while the travelers get outside from both sides of the cars. 

The design reduced door-related accidents and injuries. Moreover, it protected drivers and other people from sudden life loss. 

Specific design

The manufacturing companies of single-door cars have a specific layout for these automobiles. They install it on these coupes because they have small dimensions. 

They have slope-like roofs and specific cabins. Also, they have single doors which have particular dimensions. 

Their widths are sufficient for one person. Such automobiles have specific wheelbases and limited weight ranges.

Is it legal to drive one-door cars?

The production of one-door cars stopped several years ago. The automobiles have upgraded to four-door vehicles.

It is challenging to define the name of one door car. But, several people and automobile manufacturers call these vehicles coupe because they have a single door.
