Colombia has an exchange agreement with Spain � but it is not automatic
The DGT includes Colombia in its list of countries with a license-exchange agreement. That means the procedure exists, but it is not resolved in the same way for every category.
The key point is this: knowing the agreement exists is not enough. You also need to understand what changes depending on the vehicle category you want to preserve in Spain.

What changes between car categories and truck or bus categories
In the DGT public table, car or motorcycle categories without extra tests are processed through fee 2.3 at . Truck or bus categories linked to C or D usually require additional tests and are processed through fee 2.1 at 94.05 euros.
