What Evidence Do You Need After a Catastrophic Truck Crash?<\/h2>\n

Here is what most people don’t know. Some of the most important evidence in a truck crash can be legally erased within days<\/strong>. This can happen before you even leave the hospital.<\/p>\n

A truck’s onboard computer can record over crash data on its next trip. Driver logs and dispatch messages are kept for only a short time. A wrecked truck can be repaired, sold, or scrapped. Once that proof is gone, you usually can’t get it back.<\/p>\n

That is why the best move after a serious truck crash is often the fastest one. Someone must send a letter of preservation<\/strong> (also called a spoliation letter). This letter legally tells the trucking company to keep everything.<\/p>\n

This guide explains what evidence matters. It shows how quickly proof can vanish. And it explains how the preservation letter works.<\/p>\n

Maybe you are healing from a spinal cord injury. Maybe you are caring for someone with a brain injury, or grieving a death. You should not have to chase this proof alone.<\/p>\n

This page is general information, not legal advice about your specific case.<\/em><\/p>\n\n

Start here: the preservation letter and why speed protects your case<\/h2>\n

A letter of preservation<\/strong> is a formal written demand. It tells the trucking company (and its insurer) to keep all evidence from the crash. They must not change, repair, or destroy anything.<\/p>\n

Once a company gets this letter, destroying evidence can cause legal trouble. A court can tell a jury to assume the missing evidence would have hurt the company. This penalty is called a spoliation<\/em> sanction. That is where the letter gets its nickname.<\/p>\n

Why the rush? Federal rules only require companies to keep some records for a short time:<\/p>\n
