As a Highly Skilled Migrant, and if you use the 30% rule, you can easily convert your South African driver license to a Dutch one, without having to take driving lessons. The first 180 days after arrival, you can use your South African driver license.
When the 30% rule takes effects (approximately after 3 months), you can convert your old driver license to a Dutch one. This also applies to your possible partner.
Oh, and keep in mind, we drive at the ‘right’ side of the road 😉
