By Marisa TaylorWASHINGTON (Reuters) - Elon Musk's brain-implant company Neuralink was fined for violating U.S. Department of Transportation (DOT) rules regarding the movement of hazardous materials, according to records from the federal agency reviewed by Reuters. DOT fined the company a total of $2,480, an amount lower than what was initially assessed because the company agreed to fix the problems, the records show. A spokesperson with Pipeline and Hazardous Materials Safety Administration, the DOT agency that investigated Neuralink, confirmed the violations and fine, and said the inquiry is now closed. The records do not say why Neuralink would need to transport hazardous materials or whether any harm resulted from the violations. DOT found no evidence that Neuralink had shipped anything containing an infectious substance, the new records reviewed by Reuters said.
