Could the electric tuk-tuk be a success in Sri Lanka?

There are over one million tuk-tuks (also known as auto rickshaws) in Sri Lanka.

They are cheap to use but can also be very polluting.

But will they take off?

The Travel Show's Lucy Hedges looks at the technology and test drives an electric vehicle with tuk-tuk driver Thushari Medagamage to find out more.
