April 30 (Reuters) - U.S. truckmaker PACCAR Inc ( PCAR )

beat first-quarter profit estimates on Tuesday, on the back of

robust demand from its trucks and parts segments, benefiting an

uptick in infrastructure spend.

PACCAR ( PCAR ), which builds Kenworth, Peterbilt and DAF trucks,

expects industry retail sales in the U.S. and Canada for its

Class 8 trucks, to be between 250,000 and 290,000 in 2024.

"North American truck demand is benefiting from increased

infrastructure spending," said Mike Dozier, PACCAR's ( PCAR ) executive

vice president.

The company said it was also investing in production

capacity and developing next-generation powertrains and

connected systems, which are expected to drive aftermarket parts

growth.

The Bellevue, Washington-based company reported a adjusted

profit of $2.25 per share for the quarter ended March 31, above

LSEG estimates of $2.17.

Net sales and revenue for the first quarter was $8.74

billion, above analysts' average expectation of $8.24 billion.
