Before you plan anything else, you have to know exactly what you're moving. Measuring your load accurately — length, width, height and gross vehicle weight — is the foundation every later decision rests on, and guessing here is how expensive mistakes begin.
The key is knowing where 'standard' ends and 'abnormal' begins. Once any dimension crosses the legal tolerance — width beyond roughly 2.55 m, height beyond about 4.0 m, or weight over the ceiling — your transport is classified as oversized and a special permit becomes mandatory.
A permit for such a move is issued by the CSDD, Latvia's road-safety authority, and the details you measured feed straight into that application. Precise figures aren't bureaucratic box-ticking; they determine your route, your escort needs and your fees.
Get the measurements right and everything downstream is smoother. Record them carefully, keep the documentation with the vehicle, and treat this first step as the most important one in the whole process.
